Abstract (sommario):
Calf thymus DNA adsorbed on a rough gold substrate or on an atomically smooth gold (111) surface has been investigated by collecting its unique Raman fingerprints using either surface-enhanced Raman scattering (SERS) or tip-enhanced Raman scattering (TERS). A monolayer coverage of DNA strands adsorbed at both the irregular rough edges of evaporated gold grids and at gold nanoparticles is detected by SERS. Highly improved sensitivity down to single DNA strand spectroscopic determination is accomplished by TERS providing an enhancement factor of at least 1400. Based on our experimental results, we propose that TERS is a promising technique to study the DNA–drug molecule interaction on the level of a single DNA strand.

Abstract (sommario):
A fiber-optic system was developed for exciting and collecting surface-enhanced Raman scattering (SERS) signals generated from a sensing plate tip having silver-coated microparticles deposited on a glass support. Various fiber parameters, such as fiber type, fiber-substrate geometry, and other experimental parameters, were investigated to obtain the optimum conditions for the SERS fiber-optic device. In addition, analytical figures of merit relevant to the performance of the SERS fiber-optic sensor, such as SERS spectral characteristics, reproducibility, linear dynamic range, and limit of detection, were also investigated.

Abstract (sommario):
Cette thèse a pour objectif le développement de la spectroscopie Raman exaltée de pointe (TERS) pour des applications en milieux liquides, et plus particulièrement pour l’étude de membranes lipidiques et de protéines amyloïdes qui sont impliquées dans des maladies neurodégénératives comme la maladie d’Alzheimer. La TERS s’affranchit de la limite de diffraction de la spectroscopie Raman conventionnelle en combinant la haute résolution spatiale de la microscopie à sonde locale et la spécificité chimique de la spectroscopie Raman exaltée de surface (SERS). En utilisant une pointe de microscope à sonde locale métallisée et effilée au niveau nanométrique, la TERS génère une exaltation localisée du signal Raman au sommet de la pointe. Ceci permet l’étude de biomolécules optiquement non-résonnantes à l’échelle nanométrique sans marquage moléculaire et de manière non-destructive. Les défis clés qui sont traités dans ce travail incluent la fabrication de pointes actives en TERS, l’optimisation d’un nouveau système TERS en réflexion totale interne (RTI) pour des utilisations en environnements liquides, et l’exploitation de données complexes obtenues par imagerie TERS hyperspectrale. Des protéines amyloïdes sous forme de fibrilles de protéine Tau ont été étudiées au moyen de notre instrument de RTI-TERS en prenant des fibrilles induites par de l’héparine comme référence pour évaluer la performance du système. Des études TERS de fibrilles Tau induites par de l’ARN ont donné un aperçu des mécanismes de formation sous-jacents des fibrilles amyloïdes. Par ailleurs, ces données ont été utilisées pour explorer le potentiel des méthodes chimiométriques, telles que l’Analyse en Composantes Principales (ACP) et l’Analyse en Cluster Hiérarchique (ACH), pour leur analyse fine. Ces méthodes ont été évaluées dans le contexte des méthodes plus traditionnelles de sélection de pics individuels. Cette thèse détaille aussi le développement d’un système RTI-TERS compatible avec le milieu liquide et son application à l’étude de bicouches lipidiques supportées en milieux aqueux. Cette avancée permet la caractérisation nanométrique de membranes lipidiques dans des milieux biologiquement pertinents et plus réalistes que l’air. Dans la perspective de futurs travaux examinant les interactions protéines-lipides, ces innovations sont cruciales pour comprendre la formation des fibrilles amyloïdes et leurs effets délétères sur les cellules neuronales. Au final, cette thèse a amélioré la TERS en tant qu’outil pour étudier les structures biomoléculaires à l’échelle nanométrique dans le contexte des maladies neurodégénératives, et le système RTI-TERS optimisé fournit une plateforme pour de futures recherches dans des applications biologiques et biomédicales
The aims of this thesis are the development of tip-enhanced Raman spectroscopy (TERS) for applications in liquid media, specifically for the study of lipid membranes and amyloid proteins which are implicated in neurodegenerative diseases like Alzheimer’s. TERS overcomes the diffraction limit of conventional Raman spectroscopy by combining the high spatial resolution of scanning probe microscopy with the chemical specificity of surface-enhanced Raman spectroscopy (SERS). By employing a metal-coated nano-tapered scanning probe microscopy probe tip, TERS generates a localised enhancement of the Raman signal at the tip apex. This enables the study of optically non-resonant biomolecules at the nanoscale in a label-free and non-destructive manner. The key challenges that are addressed in this work include the fabrication of TERS-active tips, the optimisation of our novel total-internal reflection (TIR)-TERS system for use in liquid environments, and the handling of the complex data obtained from hyperspectral TERS imaging. Amyloid proteins in the form of Tau fibrils were studied using this TIR-TERS setup with heparin-induced Tau fibrils being a benchmark for evaluating the performance of the system. TERS studies of RNA-induced Tau fibrils provided insight into the underlying formation mechanisms of amyloid fibrils. In addition, these data were used to explore the use of chemometric methods, such as Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA), for their fine analysis. These methods were evaluated in the context of more traditional peak-picking methods. This thesis also details the development of a liquid-compatible TIR-TERS system and its application to the study of supported lipid bilayers in aqueous media. This advancement enables the nanoscale investigation of lipid membranes in biologically relevant media, which is more representative compared to TERS in air. With the outlook of future works investigating protein-lipid interactions, these innovations are crucial for understanding amyloid fibril formation and their deleterious effects on neuronal cells. To conclude, this thesis enhances TERS as a tool for studying biomolecular structures in the context of neurodegenerative diseases at the nanoscale, and the optimised TIR-TERS system provides a platform for future research in biological and biomedical applications

Abstract (sommario):
L'analyse in situ d'interfaces électrochimiques à l'échelle nanométriques est un enjeu majeur pour la compréhension des mécanismes de transferts de charges et d'électrons dans les domaines du stockage d'énergie ou de l'électrocatalyse. Ce travail a permis le développement de la spectroscopie Raman exaltée de pointe (TERS) en milieu liquide et en conditions électrochimiques. Le TERS permet l'analyse de la structure de molécules ou de matériaux à l'échelle nanométrique du fait de l'exaltation localisée du champ électrique à l'extrémité d'une sonde de microscope à effet tunnel (STM) en or ou en argent. Un dispositif reposant sur l'illumination d'une pointe au travers d'un solvant organique a démontré la possibilité d'imager les inhomogénéités d'une monocouche auto-assemblée sur or. Une seconde approche reposant sur l'exaltation du signal Raman à l'apex d'une pointe de taille nanométrique utilisée comme microélectrode (spectroscopie Raman exaltée de surface de pointe, tip SERS) a permis de suivre la réduction d'une monocouche auto-assemblée et d'améliorer la compréhension de son mécanisme. Afin d'imager la surface d'une électrode polarisée, le couplage d'un STM utilisant une pointe TERS en conditions électrochimiques a montré une résolution latérale de moins de 8 nm pour sonder de variations locales de l'exaltation du champ électromagnétique induites par des singularités géométriques de surface. Par ailleurs, l'analyse TERS de couches organiques formées à partir de sels d'aryldiazoniums a permis de montrer des différences de structures selon type de greffage. Ce travail constitue donc une avancée majeure pour l'analyse locale de surfaces modifiées
The in situ investigation of electrochemical interfaces structures at the nanoscale is a key element in the understanding of charge and electron transfer mechanisms e.g. in the fields of energy storage or electrocatalysis. This thesis introduces the implementation of tip-enhanced Raman spectroscopy (TERS) in liquid and in electrochemical conditions enabling the nanoscale analysis of electrified solid/liquid interfaces through the strong and local electric field enhancement at gold or silver scanning tunneling microscopy (STM) probes. The ability of TERS to image inhomogeneities in the coverage density of a self-assembled monolayer (SAM) through a layer of organic solvent on gold was demonstrated. A TERS-inspired analytical tool was also developed, based on a TERS tip used simultaneously as a single-hot spot surface-enhanced Raman spectroscopy (SERS) platform and as a microelectrode (EC tip SERS). The reduction of an electroactive SAM could then be monitored by electrochemical and in situ SERS measurements. In situ electrochemical STM-TERS was also evidenced through the imaging of local variations of the electric field enhancement on peculiar sites of a gold electrode with a lateral resolution lower than 8 nm. Finally TERS also demonstrated to be efficient in investigating the structure of organic layers grafted either by electrochemical reduction or spontaneously. This work is therefore a major advance for the analysis of functionalized surfaces

Abstract (sommario):
Surface- and tip-enhanced resonant Raman scattering (resonant SERS and TERS) by optical phonons in a monolayer of CdSe quantum dots (QDs) is demonstrated. The SERS enhancement was achieved by employing plasmonically active substrates consisting of gold arrays with varying nanocluster diameters prepared by electron-beam lithography. The magnitude of the SERS enhancement depends on the localized surface plasmon resonance (LSPR) energy, which is determined by the structural parameters. The LSPR positions as a function of nanocluster diameter were experimentally determined from spectroscopic micro-ellipsometry, and compared to numerical simulations showing good qualitative agreement. The monolayer of CdSe QDs was deposited by the Langmuir–Blodgett-based technique on the SERS substrates. By tuning the excitation energy close to the band gap of the CdSe QDs and to the LSPR energy, resonant SERS by longitudinal optical (LO) phonons of CdSe QDs was realized. A SERS enhancement factor of 2 × 103 was achieved. This allowed the detection of higher order LO modes of CdSe QDs, evidencing the high crystalline quality of QDs. The dependence of LO phonon mode intensity on the size of Au nanoclusters reveals a resonant character, suggesting that the electromagnetic mechanism of the SERS enhancement is dominant. Finally, the resonant TERS spectrum from CdSe QDs was obtained using electrochemically etched gold tips providing an enhancement on the order of 104. This is an important step towards the detection of the phonon spectrum from a single QD

Abstract (sommario):
Nanomaterials have the remarkable characteristic of displaying physical properties different from their bulk counterparts. An additional degree of complexity and functionality arises when oxide nanoparticles interact with metallic nanostructures. In this context the Raman spectra due to plasmonic enhancement of iron oxide nanocrystals are here reported showing the activation of spin-waves. Iron oxide nanoparticles on gold and silver tips are found to display a band around 1584 cm−1 attributed to a spin-wave magnon mode. This magnon mode is not observed for nanoparticles deposited on silicon (111) or on glass substrates. Metal–nanoparticle interaction and the strongly localized electromagnetic field contribute to the appearance of this mode. The localized excitation that generates this mode is confirmed by tip-enhanced Raman spectroscopy (TERS). The appearance of the spin-waves only when the TERS tip is in close proximity to a nanocrystal edge suggests that the coupling of a localized plasmon with spin-waves arises due to broken symmetry at the nanoparticle border and the additional electric field confinement. Beyond phonon confinement effects previously reported in similar systems, this work offers significant insights on the plasmon-assisted generation and detection of spin-waves optically induced

Abstract (sommario):
Depuis les années 2000, le développement de la spectroscopie Raman à exaltation de pointe (TERS) a permis l’accès de manière extrêmement localisée aux propriétés structurales et moléculaires à la surface de la matière et à des analyses physico-chimiques combinées. La technologie TERS associe les techniques de microscopie à sonde locale - ici le microscope à force atomique (AFM) - avec le champ proche optique. Elle bénéficie en particulier de la génération, à la surface métaux nobles, de plasmons de surface à l’origine d’exaltation d’ondes électromagnétiques pouvant être confinées dans un volume sub-longueur d'onde à l'extrémité des sondes AFM-TERS. Aujourd'hui le principal verrou technologique en TERS est la conception des sondes AFM en termes de reproductibilité à échelle nanométrique, et de fabrication en série. Ce travail de thèse effectué dans le cadre d’une thèse CIFRE (HORIBA Scientific) a eu pour but de concevoir un nouveau type de sonde AFM-TERS répondant aux exigences de performances et de fabrication actuelles. Pour atteindre cet objectif, une étude de simulation numérique a conduit à proposer une nanostructuration métallique de l’extrémité d’un levier AFM, afin de conduire à une exaltation électromagnétique optimisée. Un procédé de nano- et micro-fabrication a été développé au sein de la plateforme de micro et nano-fabrication de l'IEMN, combinant lithographie électronique et optique, évaporation métallique et gravure sur wafers silicium. Il permet la réalisation en série de sondes AFM dont chaque extrémité est composée d'une nano-antenne métallique de taille sub-longueur d'onde, composée d'un nanodisque supportant un nanocône. La méthode de fabrication proposée permet un contrôle des réponses plasmoniques en termes d’amplification du champ et d’accordabilité de la résonance, qui sont la clé des performances en spectroscopie Raman à exaltation de pointe. Une étude sur l’évaporation inclinée lors du procédé de nano-fabrication développé par lithographie électronique a également été réalisé dans le but de contrôler la forme des nanoparticules – de forme conique à cylindrique avec des parois poreuses -- isolées ou en réseaux denses. Les simulations numériques suggèrent que de tels objets peuvent être des candidats potentiels pour le TERS ou le SERS (spectroscopie Raman à exaltation de surface)
Since the start of the 2000s the evolution of tip-enhanced Raman spectroscopy (TERS) has enabled the simultaneous measurement of localized structural, molecular, and physicochemical properties. TERS technology combines scanning probe microscopy -- atomic force microscopy (AFM) -- with near field optical microscopy. The combined technique is referred to as AFM-TERS. The technique harnesses and exploits the generation of surface plasmons on metal surfaces. These plasmons lead to the generation of confined electromagnetic waves in a sub-wavelength volume at the very tip of the AFM-TERS probe. The main technological challenge today is the design and optimization of an AFM-TERS probe having nanometer-sized dimensions -- and the controlled, reproducible batch fabrication of such structures. The objective of the work presented in this PhD thesis was to design, fabricate, and characterize a new type of AFM probe capable of bettering the current state-of-the-art performances. The PhD was carried out in collaboration with HORIBA and funded partly by a French ‘CIFRE’ grant. In order to meet these objects, comprehensive numerical modelling led to the design of an optimized metal nanostructuring having maximum electromagnetic exaltation -- placed at the extremity of a silicon-based AFM cantilever. A new combined micro and nano fabrication process was developed to achieve this -- to be performed using the existing equipment found in the IEMN cleanroom. The process encompasses techniques such as masking using electron beam (ebeam) lithography and UV photolithography, thermal evaporation of metals and ‘lift-off’ techniques, and highly-controlled dry etching of small silicon mesas structures and deep etching for MEMS cantilever releasing. The process enables the batch-fabrication manufacture of AFM-TERS probes containing matter on the millimeter scale (the silicon probe support), the micrometer scale (the silicon cantilever), and the nanometer scale (the combined metallic disk and cone having sub-wavelength dimensions). This method allows nanostructuring on the optical/plasmonic behavior of TERS probes, the key factor which will lead to higher performance in TERS. Finally, a further study concerning the inclined evaporation of metallic nanostructures via an ebeam-derived lithographic shadow mask was performed in order to control the size and shape of the nanostructuring. The study proved this approach to be feasible. Furthermore, numerical modelling of such structures suggests that they are potential original candidates for both TERS and SERS (surface-enhanced Raman spectroscopy)

Ce travail de thèse s'articule autour des phénomènes d'exaltation de la diffusion Raman grâce aux propriétés optiques des métaux nobles (Or et Argent). Des expériences de Spectroscopie Raman Exaltée de Surface (SERS : Surface Enhanced Raman Spectroscopy) et de Spectroscopie Raman Exaltée par sonde locale (TERS : Tip Enhanced Raman Spectroscopy) ont permis l'exploration des ces phénomènes. Le premier volet de ce travail a consisté en la préparation de substrats « SERS-actifs » et en l'analyse de leurs pouvoir exaltant. Trois types de substrats ont été élaborés au laboratoire afin d'étudier les paramètres d'influence (structuration de la surface, longueur d'onde et polarisation de la lumière incidente, nature du métal, etc...). Le second volet du travail a été consacré à la mise en place d'un dispositif TERS. La conception des pointes métalliques a fait l'objet d'une attention particulière. De plus, un module a été élaboré afin d'associer un système de nano-positionnement de la pointe à un Raman confoncal commercial. Ce module a aussi été conçu pour permettre de focaliser le faisceau laser à l'extrémité de la nano-sonde métallique. La conception des outils ainsi que la compréhension des résultats expérimentaux sont corrélés à une analyse numérique. Les sources électromagnétiques (plasmons de surface et effet de pointe) de l'amplification de la diffusion Raman sont étudiées avec l'appui de simulations numériques par la méthode des éléments finis. Enfin les aspects chimiques des phénomènes d'exaltation sont abordés par DFT (Density Functiunal Theory).

Ce travail de thèse se focalise sur le couplage du microscope à force atomique haute–vitesse (HS-AFM) et de la spectroscopie Raman exaltée de surface (SERS) pour la détection des biomolécules. Nous avons élaboré un protocole de fabrication pour produire les substrats “SERS-actifs”. L’efficacité des substrats de nanoparticules cristalline d’or, d’argent ou bimétallique argent–or a été évaluée. Nous avons étudié l’impact des propriétés optiques et morphologiques des substrats sur l’intensité Raman en analysant des échantillons tests tels que la bipyridine éthylène et le bleu de méthylène. Nous nous sommes interessés à trois problematiques biologiques distinctes par analyses HS-AFM et SERS. Dans un premier cas, nous avons détecté la signature chimique de protéine cytochrome b5. Ce travail a été suivi par des études sur le changement de conformation de la protéine de choc thermique leuconostoc oenos Lo 18 en fonction de la concentration et du pH. La dernière application consiste en l’analyse des interactions membrane – virus. Afin de réaliser les analyses simultanées Raman/AFM, nous avons adapté notre protocole de fabrication pour couvrir la surface des pointes AFM commerciales par des nanoparticules d’or cristallines. Les études de diffusion Raman exaltée par effet de pointe (TERS) ont été effectuées sur les échantillons de disulfure de molybdène pour évaluer la qualité des pointes TERS. Pour finir, nous présentons une nouvelle configuration de couplage HS-AFM et spectroscopie Raman. Nous discutons des modifications et des défis rencontrés
This thesis focuses on the coupling of High–Speed Atomic Force Microscopy (HS-AFM) and Surface Enhanced Raman Spectroscopy (SERS) for biomolecule analysis. We have designed a fabrication protocol to manufacture “SERS-active” substrates. The efficacy of gold, silver and gold-silver bimetallic crystalline nanoparticle substrates were evaluated. We have investigated the impact of optical and morphological features of the substrates on Raman signal intensity by analyzing well-known samples such as bipyridine ethylene and methylene blue molecules. We took an interest in three distinct biological problematics with HS-AFM and SERS analyses. First, we have detected the chemical signature of cytochrome b5 protein. This study was followed by the investigation of conformational changes of small heat shock leuconostoc oenos Lo 18 protein in function of pH level and concentrations. The last application consists to the analyse a membrane and a virus interaction. In order to realize simultaneous Raman/AFM analysis, we have adapted our fabrication protocol to cover the surface of commercial AFM probes by crystalline gold nanoparticles. Tip – Enhanced Raman Spectroscopy (TERS) studies were performed on molybdenum disulfide to evaluate the quality of TERS probes. In the last part of this work, we have designed a new setup to combine Ando’s HS-AFM setup with Raman spectroscopy. We present the modifications that have been carried out and the challenges that we have encountered

Tip-enhanced near-field Raman spectroscopy utilizes a metal-coated sharp tip and is based on surface-enhanced Raman scattering (SERS). Instead of the large surface enhancement from the metallic surface in SERS, the sharp metal coated tip in the tip-enhanced Raman scattering (TERS) provides nanoscaled surface enhancement only from the sample molecules in the close vicinity of the tip-apex, making it a perfect technique for nanoanalysis of materials. This article focuses on near-field analysis of some semiconducting nanomaterials and some carbon nanostructures. It first considers SERS analysis of strained silicon and TERS analysis of epsilon-Si and GaN thin layers before explaining how to improve TERS sensitivity and control the polarization in detection for crystalline materials. It also discusses ways of improving the spatial resolution in TERS.
