photoarray 22psd

Abstract

The main objective of the Optonanogen proposal is to develop a portable biosensor microsystem able to detect single nucleotide variations in human genes. The biosensor microsystem will consist of: i) an array of 20 microcantilevers produced by standar silicon micromechanical technology, ii) an optical detection system capable of measuring the cantilever movement (lasers and photodetectors). The array of lasers (VSCELs) will be fabricated by Molecular Beam Epitaxy of semiconductor compounds. The array of photodetectors will be integrated with their corresponding amplifier and signal processing circuits, after desing and fabrication of the CMOS circutry and iii) a polymer microfluidic system will be developed for reagents delivery to the biosensor
