Les lames de verre transparentes sur lesquelles on d\u00e9pose les \u00e9chantillons pour les observer au microscope n\u2019ont quasiment pas \u00e9volu\u00e9 en 200 ans d\u2019existence. Deux chercheurs de l\u2019Institut de Microtechnique de l\u2019EPFL Neuch\u00e2tel ont mis fin \u00e0 cet oubli. Ils ont d\u00e9velopp\u00e9 un nouveau type de lame qui permet de d\u00e9tecter des maladies graves \u00e0 un stade plus pr\u00e9coce.<\/h4>\n

Utilis\u00e9es dans des millions de laboratoires \u00e0 travers le monde pour les analyses m\u00e9dicales, les lames de verre pr\u00e9sentent l\u2019inconv\u00e9nient majeur de garder pour elles 70% de la lumi\u00e8re, ce qui fait qu\u2019il est parfois difficile \u2013 voire impossible \u2013 de d\u00e9tecter certaines mol\u00e9cules, \u00e0 moins qu\u2019elles ne soient pr\u00e9sentes en quantit\u00e9 importante. \u00c0 l\u2019Institut de Microtechnique de l\u2019EPFL Neuch\u00e2tel<\/a>, le chimiste des mat\u00e9riaux Rapha\u00ebl Barbey et l\u2019ing\u00e9nieur optique Nicolas Descharmes ont d\u00e9velopp\u00e9 un nouveau type de lame en verre qui permet d\u2019augmenter jusqu\u2019\u00e0 25 fois la quantit\u00e9 de lumi\u00e8re obtenue par rapport aux lames classiques. Cela signifie que, dans une situation id\u00e9ale, ces lames r\u00e9volutionnaires seraient capables de d\u00e9tecter la pr\u00e9sence d\u2019une seule mol\u00e9cule, l\u00e0 o\u00f9 il en faudrait 25 sur une lame standard. Des propri\u00e9t\u00e9s optiques uniques<\/strong> Gr\u00e2ce \u00e0 leur structure, ces nouvelles lames ont la capacit\u00e9 de contr\u00f4ler l\u2019environnement \u00e9lectromagn\u00e9tique de l\u2019\u00e9chantillon. Cela permet, notamment, d\u2019augmenter la quantit\u00e9 de lumi\u00e8re \u00e9mise par les fluorophores et de rediriger la totalit\u00e9 de la lumi\u00e8re vers le d\u00e9tecteur. Les images obtenues sont donc plus claires qu\u2019auparavant ou peuvent \u00eatre acquises de fa\u00e7on beaucoup plus rapide. Diagnostic pr\u00e9coce<\/strong> L\u2019invention de Descharmes et Barbey pourrait permettre l\u2019identification pr\u00e9coce de certains types de cancers, ainsi que la simplification de la lecture et de l\u2019archivage des lames histopathologiques utilis\u00e9es lors de l\u2019analyse de biopsie. Les deux chercheurs travaillent actuellement \u00e0 l\u2019industrialisation de leur technologie, en collaboration avec le CSEM<\/a>, le Centre suisse d\u2019\u00e9lectronique et de microtechnique.<\/p>\n","protected":false},"excerpt":{"rendered":"
