d\u00e9velopper un capteur optique int\u00e9gr\u00e9 innovant utilisant la spectroscopie dans le moyen infrarouge pour d\u00e9tecter des compos\u00e9s organiques volatils (COVs). Ces capteurs sont fabriqu\u00e9s \u00e0 partir de couches en silicium poreux (SiP) afin de b\u00e9n\u00e9ficier des pores ouverts permettant une d\u00e9tection en volume pour obtenir une tr\u00e8s faible limite de d\u00e9tection. Ce travail de th\u00e8se a \u00e9t\u00e9 bas\u00e9 principalement sur la chimie de surface et le d\u00e9veloppement des diff\u00e9rents protocoles de fonctionnalisation chimique, organique et inorganique, des monocouches de SiP pour la d\u00e9tection de\u00a0 deux mol\u00e9cules cibles dans le MIR. Dans une premi\u00e8re approche (inorganique), des nanostructures hybrides (Cu\/SiP) et (TiO2\/SiP) ont \u00e9t\u00e9 d\u00e9velopp\u00e9es pour la d\u00e9tection du dim\u00e9thyl m\u00e9thyl phosphonate (DMMP), un simulant du gaz sarin. Dans une approche organique, des groupes fonctionnels d\u2019acide boronique ont \u00e9t\u00e9 introduits par r\u00e9action d\u2019hydrosilylation dans les SiP pour la d\u00e9tection du glucose.<br \/>\nLes nanostructures hybrides d\u00e9velopp\u00e9es ont d\u00e9montr\u00e9 leurs potentiels de d\u00e9tection dans le moyen infrarouge par caract\u00e9risation FT-IR, permettant la d\u00e9tection du DMMP et de glucose dans cette r\u00e9gion.<\/p>\n<\/blockquote>\n<h5>Abstract:<\/h5>\n<blockquote>\n<p>This thesis was carried out within the framework of a MID-VOC project financed by the French National Research Agency (ANR) which aims at developing an innovative integrated optical sensor using mid-infrared spectroscopy to detect volatile organic compounds (VOCs).\u00a0 These sensors are made from porous silicon (SiP) layers in order to provide open pores for volume sensing to obtain a very low detection limit. This thesis work was mainly based on surface chemistry and the development of different chemical functionalization protocols, organic and inorganic, of SiP monolayers for the detection of two target molecules in the MIR.\u00a0 In a first (inorganic) approach, hybrid (Cu\/SiP) and (TiO2\/SiP) nanostructures were developed for the detection of dimethyl methyl phosphonate (DMMP), a simulant of sarin gas.\u00a0 On the other hand, in an organic approach, boronic acid functional groups were introduced by hydrosilylation reaction into SiPs for glucose detection. The developed hybrid nanostructures have demonstrated their mid-infrared sensing potentials by FT-IR characterization, revealing the presence of unique fundamental vibrational molecular fingerprints of DMMP and glucose in this region.<\/p>\n<\/blockquote>\n<\/div><\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"author":20,"featured_media":55616,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[87,65,84,316],"tags":[],"class_list":["post-55612","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-agenda-en","category-agenda","category-agenda-en-en","category-theses-2022"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/55612","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=55612"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/55612\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media\/55616"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=55612"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=55612"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=55612"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
