Real-time PCR in a plastic chip based on solid state FRET.

ABSTRACT

We show a novel solid state optical detection platform, integrated in a plastic biochip, based on colloidal nanocrystal FRET donors. The approach exploits a "smart" polymeric layer with both optical and biorecognition properties that allows real-time monitoring of biomolecular interactions and quantitative analyses of real-time PCR. The proposed strategy, demonstrated here for DNA detection, may open interesting perspectives for a wide range of applications, such as for proteomic studies.
