MICROFLUIDIC PLASMONIC DEVICE BASED ON BI-PYRAMID GOLD NANOPARTICLES

摘要

The invention relates to a process for preparing a microfluidic plasmonic device used in the field of biosensors. According to the invention, the process consists in integrating, inside a microfluidic polydimethylsiloxane channel, a nanoparticulate film formed on an amino-silanized glass substrate through a process of self-assembling Au nanoparticles of pyramidal shape available in aqueous solution, with controllable optical properties and sensorial capacities, the resulting device being suitable for simultaneous detection and identification of the molecules of interest in real time.
