Texte intégralOptical 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

Texte intégralThe 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.

Chen, Feixiong. « Dual functionalization of magnetic nanoparticles by electroactive molecules and antibodies for platelet antigens detection ». Thesis, Lyon, 2017. http://www.theses.fr/2017LYSEC033/document.
Texte intégralFetal/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).
