SYSTEM FOR BIODETECTION APPLICATIONS

摘要

The invention relates to a system for biodetection applications, which comprises two basic elements, a substrate having a functionalised surface, and a nanoparticle, and which can strengthen the plasmonic effect of the nanoparticle. The invention also relates to a bio-sensor that includes said system, and to the method for detecting and quantifying a target analyte selected in a sample using said system. The invention further relates to a device that can detect the strengthened opto-plasmonic effect of the nanoparticles using the system according to the invention, or combine the detection of said opto-plasmonic effect with the analysis of the changes in the mechanical characteristics of the substrate.
