Abstract:
We propose an electrical detection method for detecting the various bio-molecules effectively with microcantilevers. The piezoresistive microcantilevers were fabricated employing surface micromachining technique that has attractive advantages in terms of cost efficiency, simplicity, and ability of fabricating in array. The fluid cell system for injection of bio-molecular solution is fabricated using polydimethylsiloxane (PDMS) and a fused silica glass. The microcantilever is deflected with respect to the difference of the surface stress caused by the formation of self-assembled bio-molecules on the gold coated side of the microcantilever. We confirmed that the deflections occurred by the bio-molecule adsorption and microcantilever can be widely used to a &-TAS and a lab-on-a-chip as a sensor for the potential detection of various biomolecules.

Abstract:
The detection of long-chain biomolecules on mineral surfaces is presented using an atomic force microscope (AFM). This is achieved by using the AFM’s ability to manipulate molecules and measure forces at the pico-newton scale. We show that a highly characteristic force-distance signal is produced when the AFM tip is used to detach long-chain molecules from a surface. This AFM force spectroscopy method is demonstrated on bio-films, spores, fossils and mineral surfaces. The method works with AFM imaging and correlated tip enhanced infrared spectroscopy. The use of AFM force spectroscopy to detect this class of long chain bio-markers has applications in paleontology, life detection and planetary science.

Abstract:
Resonant micro/nanoelectromechanical systems (MEMS/NEMS) with on-chip integrated excitation and readout components, exhibit exquisite gravimetric sensitivities which have greatly advanced the bio/chemical sensor technologies in the past two decades. This paper reviews the development of integrated MEMS/NEMS resonators for bio/chemical sensing applications mainly in air and liquid. Different vibrational modes (bending, torsional, in-plane, and extensional modes) have been exploited to enhance the quality (Q) factors and mass sensing performance in viscous media. Such resonant mass sensors have shown great potential in detecting many kinds of trace analytes in gas and liquid phases, such as chemical vapors, volatile organic compounds, pollutant gases, bacteria, biomarkers, and DNA. The integrated MEMS/NEMS mass sensors will continuously push the detection limit of trace bio/chemical molecules and bring a better understanding of gas/nanomaterial interaction and molecular binding mechanisms.

Abstract:
Les biocapteurs optiques ont connu une évolution sans précédent au cours des dernières années, principalement en raison de la forte interaction entre la biotechnologie, l’optique et la chimie des matériaux. Dans cette thèse, deux différentes plates-formes de biocapteurs optiques ont été conçues pour la détection sensible et spécifique des biomolécules. Plus précisément, le premier système de détection optique est construit sur la base de la bioluminescence de cellules bactériennes d'Escherichia coli génétiquement modifiées. L’émission de lumière induite par cette interaction peut donc être utilisée pour la détection des substances toxiques. Le second système utilise des nanoparticules de métaux précieux (or et argent) aux propriétés plasmoniques accordables qui permettent de sonder les interactions des biomolécules spécifiques à l'interface nano-bio par la résonance plasmonique de surface (LSPR). Ces nanoparticules ont été obtenues par traitement thermique à haute température d’un film métallique déposé sur du verre à l’aide d’une grille de TEM ou déposé sur une couche de bactéries fixée sur le verre. Après une optimisation appropriée des nanostructures métalliques en termes de morphologie et de fonctionnalisation, une sensibilité élevée et une grande spécificité peuvent être simultanément obtenues avec ces immunocapteurs plasmonique. Ces deux plateformes ont été utilisées pour détecter des pesticides comme le carbofuran et l’atrazine
Optical biosensors have witnessed unprecedented developments over recent years, mainly due to the lively interplay between biotechnology, optical physics and materials chemistry. In this thesis, two different optical biosensing platforms have been designed for sensitive and specific detection of (bio)molecules. Specifically, the first optical detection system is constructed on the basis of bioluminescence derived from engineered Escherichia coli bacterial cells. Upon stressed by the toxic compounds, the bacterial cells produce light via a range of complex biochemical reactions in vivo and the resulted bioluminescent evolution thus can be used for toxicant detection. The bacterial bioluminescent assays are able to provide competitive sensitivity, while they are limited in the specificity. Therefore, the second optical detection platform is built on the localized surface plasmon resonance (LSPR) immunosensors. In this optical biosensor, the noble metal (gold and silver) nanoparticles with tunable plasmonic properties are used as transducer for probing the specific biomolecules interactions occurred in the nano-bio interface. These nanoparticles were obtained after a high temperature thermal treatment of an initially thin-metallic film deposited on a glass substrate through a TEM grid or on a bacteria layer fixed on the glass. After appropriate optimization on metal nanostructures morphology and surface biomodification, the applicable sensitivity and specificity can be both guaranteed in this LSPR immunosensor

Abstract:
This thesis demonstrates novel nanoscale analytical platforms for the selective and sensitive detection of biomolecules for pharmaceutical, environmental and biomedical applications. The new platforms comprised functionalized nanomaterials, disposable sensors and portable detectors for the combined Raman and electrochemical determination of biomolecules. The new nanosensing methodology utilizes the thiol chemistry of biomolecules for their label-free detection by SERS and DPV. Therefore, it can be applied to numerous biomolecules that have disulfide bonds structure. In terms of sensitivity, sample processing, analysis time and cost, the new methodology has significant advantages over the other current techniques such as chromatography and enzyme-linked immunosorbent assay.

Abstract:
2011/2012
The objective of this doctoral research is the development and the implementation of SERS-active substrates with biological samples. The substrates consist in coated silver nanoparticles synthesized by chemical reduction of a silver salt. The biological samples are the anionic chromophore bilirubin and two heme protein, the cationic cytochrome-c and the anionic protein cytochrome b5. In the first part of this work, positively charged nanoparticles were prepared by coating citrate-reduced silver nanoparticles with the cationic polymer poly-L-lysine and were employed with bilirubin in the experiments listed below:  detection of nanomolar bilirubin concentrations in aqueous solutions, showing that the SERS intensity increases linearly with concentration in a range from 10 nM to 200 nM, allowing quantitative analysis of bilirubin aqueous solutions.  indirect quantification of bilirubin cellular up-take, demonstrating the ability to detect the bilirubin also in a buffer solution suitable for cell growth with pH 7.4. Since the bilirubin quantification at this pH is no longer possible, the poly-L-lysine was substituted by two polymers with a quaternary nitrogen atom.  bilirubin measurement in serum, but TEM images highlights the formation of a albumin layer around the nanoparticles, blocking the interaction between bilirubin and the nanoparticles. Hence the citrate-reduced silver nanoparticles were coated with an hydrophobic capping and re-dispersed in hexane, to avoid the albumin layer around the nanoparticles. In the second part of this doctoral thesis, silver nanoparticles were prepared via seed growth method and subsequently coated with chitosan or silica in order to obtain positively or negatively charged nanoparticles respectively. Such substrates enhance the spectrum of the cytochrome-c and cytochrome-b5 on polished silver electrode without directly interact with the protein. Thanks to the presence of chitosan or silica coated nanoparticles, the cytochrome-c and cytochrome-b5 can be detected on a gold substrate.
L’obiettivo di questo dottorato è lo sviluppo e l’implementazione di substrati SERS attivi con campioni biologici. Nanoparticelle di argento ricoperte sono state scelte come substrati. I campioni biologici analizzati sono la bilirubina e due proteine eme, il citocromo-c (cationico) e il citocromo-b5 (anionico). Nella prima parte di questo lavoro le nanoparticelle di argento sono state preparate usando come agente riducente il citrato e successivamente sono state ricoperte con un polimero cationico, la poli-lisina. Le nanoparticelle cariche positivamente così ottenute sono state impiegate con la bilirubina nei seguenti esperimenti:  rilevazione di concentrazioni nano-molari di bilirubina in soluzioni acquose, dimostrando che per concentrazioni comprese tra 10 e 200 nM, l’intensità degli spettri SERS aumenta linearmente con la concentrazione. È quindi possibile l’analisi quantitativa di bilirubina in soluzioni acquose.  quantificazione indiretta dell’assorbimento cellulare di bilirubina, documentando la possibilità di rilevare la bilirubina in una soluzione tampone che permetta la crescita cellulare a pH 7.4. Dal momento che la quantificazione della bilirubina in questa soluzione buffer non è più possibile, la poli-lisina è stata sostituita con due polimeri che presentano un azoto quaternario.  misura della bilirubina nel siero, ma le immagini TEM evidenziano la formazione intorno alle nanoparticelle di uno strato di albumina, che impedisce l’interazione della bilirubina con le nanoparticelle ricoperte di poli-lisina. Per evitare la formazione dello strato di albumina, le nanoparticelle di argento sono state quindi ricoperte con un capping idrofobico e ridisperse in esano. Nella seconda parte di questa tesi di dottorato, le nanoparticelle di argento sono state preparate a partire da nanoparticelle di qualche nanometro e successivamente ricoperte con chitosano o silice. Lo spettro del citocromo-c e del citocromo-b5 sono stati amplificati grazie alla presenza di queste nanoparticelle senza interagire direttamente con le proteine. Grazie alla presenza delle nanoparticelle ricoperte di chitosano o silice, il citocromo-c e il citocromo-b5 sono stati misurati su un substrato d’oro.

Abstract:
Ce travail de thèse s’inscrit dans un projet plus large qui vise à développer avec le laboratoire Ampère et l’Etablissement Français du Sang un microsystème capable de réaliser un phénotypage plaquettaire pour le diagnostic de la thrombopénie néonatale. Ce microsystème doit permettre d’isoler les plaquettes du sang total et de détecter les antigènes plaquettaires présents à leur surface. L’isolation des plaquettes se fera grâce à un module de magnétophorèse et un module de diélectrophorèse. La détection sera électrochimique. Le cœur de ce travail de thèse a donc consisté à développer des nanoparticules magnétiques pour le module de magnétophorèse. Ces nanoparticules doivent permettre la capture spécifique des plaquettes et servir de marqueur pour la détection électrochimique. Pour ce faire, des nanoparticules magnétiques ont donc été doublement fonctionnalisées en une seule étape avec un anticorps anti-CD32 dirigé contre l’antigène CD32 présent à la surface des plaquettes et avec une molécule électroactive. Après optimisation des différents paramètres de greffage, les propriétés électrochimiques de ces particules ont été caractérisées. Leurs propriétés de bioreconnaissance ont été testées sur l’antigène purifié puis sur plaquettes entières. Enfin la faisabilité de la manipulation des structures nanoparticules/plaquettes par magnétophorèse avec des micro-aimants a été démontrée
Fetal/neonatal alloimmune thrombocytopenia (F/NAIT) represents a great threat to new-borns or fetus. It occurs when a woman becomes alloimmunized against fetal platelet antigens. With the aim to improve fetal and neonatal survival, in collaboration with Ampere Laboratory and Etablissement Français du Sang, we plan at developing a Point-of-Care (POC) platform for platelet phenotyping. The final POC microsystem will be able to perform magnetophoresis and dielectrophoresis for platelets isolation from whole blood, and their selective electrochemical detection allowing for their phenotyping. The development of nanoparticles (NPs) with magnetic, electrochemical and bio-selection properties is a key issue. Herein, we have focused on the elaboration of magnetic NPs bearing 1) anti-CD32 antibody for specific interaction with CD32 antigen, which is present at the surface of platelets and 2) ferrocene carboxylic acid, an electroactive molecule for detection. To achieve this, the coupling reactions of this electroactive molecule and this antibody were optimized and a one-pot reaction for double functionalization was developed. The bioactivity of the immobilized antibody was tested at the molecular and cellular level. The dual-functionalized NPs voltammetric signals were also investigated. Finally the feasibility of platelets capture and actuation by magnetophoresis with micro-magnet array were demonstrated

Present studies were subdivided in the four main categories. In the first part, Preanodized nontronite-screen printed electrode (NSPE*) was used to detect the amitrole and vitamin B6, by anodizing NSPE at 2.0 V vs. Ag/AgCl for 60s. Upon preanodization we believe the Iron ion in low oxidation become higher oxidation states and leads to effectively interaction with analyte, by the principle hard acid combine with hard base. Obtained detection limit for amitrole by SWV is 0.33 mM (S/N=3) and for Vitamin B6 is 0.35 mM (S/N=3) with the relative standard current deviation (RSD) of 2%. In the second step, NSPE* was utilized in flow injection analysis for the detection amitrole and vitamin B6. Obtained detection limit (S/N=3) for amitrole and vitamin B6 are 0.07 and 0.4 ng/20 ml with a RSD values of 0.98 and 1.13% respectively. Results indicate sensitive performance by FIA over SWV technique. In the third step, simultaneous measurement of melanin and vitamin B6 by adjusting the solution pH where the above compounds current signals were well separated, was carried out. In this method obtained recovery for some real samples is 99~103 %,indicates less interference effect of above compounds in its mixture. In the final step, Clay/lead-ruthenium oxide pyrochlore chemically modified electrode (CCME) was prepared using Ru3+ and Pb2+ ions and its effective ratio was systematically optimized. CCME was applied to effective detection of dopamine. Michaelis-Menten (MM) type of mechanism was adopted for dopamine oxidation. MM parameters like Km, kc and k''E were evaluated from LB plot analysis. Obtained detection limit by OSWV on CCME for dopamine is 0.54 nM (S/N=3).

The presented chapter is devoted to chiral biosensing using various metal nanostructures and their hybrid nanosystems with optically active bio- and organic molecules. Plasmonic nanosystems and nanostructures provide an excellent platform for label-free detection of molecular adsorption by detecting tiny changes in the local refractive index or amplification of light-induced processes in biomolecules. Based on recent theoretical and experimental developments in plasmon-enhanced local electric fields, we consider the main types of molecular-plasmonic hybrid systems capable of generating an amplified chiroptical signal for such applications as detecting the presence of certain biomolecules and (in some cases) determination of their orientation and higher-order structure.

Biosensors are considered to be devices of interest for environmental monitoring. The peculiar characteristics of biosensors allow them to complement current field screening and monitoring methods, especially when continuous, real-time, in situ monitoring is required. However, biosensors still face problems of stability, detection sensitivity, and reliability of the biomolecular recognition element. In recent years, new binding molecules have been introduced in many areas of science. In this chapter, the different natural or synthetic molecules employed in the development of biosensors for environmental monitoring are reviewed, with special emphasis on innovative (bio)receptors claimed to overcome stability concerns of traditional sensing elements. The key role of nucleic acids in the identification of new smart bioreceptors is described.

Abstract:
The introduction of nanomaterials in biosensing technology has widened the applications of nano biosensors in several fields as in the precise detection of micropollutants. A huge burden has been driven out by the micropollutants in an environment that has resulted in an alarming situation for scientists to discover innovative methods for the precise or accurate detection of micropollutants that provides sensitivity and specificity at the same time. Apart from conventionally available methods, nano biosensors provide real-time analysis and high-frequency monitoring of pollutants without much sample preparation. Nano biosensors can detect and manipulate atoms or molecules by use of nanodevices resulting in the development of biosensor devices which in turn interact with small molecules named micropollutants. This chapter aims to glance over the advancement in the fields of nano biosensors-based functionalized nanoparticles, nanotubes, or nanowires and their interaction with biorecognition materials such as enzymes, antibodies, or aptamers for the detection of aptamers.

Abstract:
Single molecule detection in solution offers the prospect of counting individual molecules within small quantities of sample for ultrasensitive chemical analysis [1] and of enabling new approaches for bio-technology applications, such as rapid DNA sequencing and the detection of rare fluorescently-labeled biomolecules. However, further developments in the techniques are required in order to move from the proof-of-principle experiments reported to date, to the level of capability required for realization of the applications. In particular, an increase in the rate at which single molecules can be efficiently detected is required.

Abstract:
By biofunctionalizing magnetic nanoparticles with bioprobes, magnetic nanoparticles are able to specifically label bio-molecules. With the association between magnetic nanoparticles and bio-molecules, the mixed-frequency AC magnetic susceptibility generated with the physical rotation of individual magnetic nanoparticles under external AC magnetic fields is reduced. This detection technology is so-called immunomagnetic reduction (IMR) assay. In the experiment, several kinds of proteins and small-molecule chemicals were detected via IMR. The characteristic curves, i.e. the reduction versus the concentration of protein/chemical, for these proteins or chemicals can be scaled to one universal curve.
