專利摘要

A bio-sensing system comprises a light source, a bio-sensing apparatus, a detecting platform, and a processing unit. A bio-sensing apparatus further comprising a substrate, a sample with at least one analyte, at least one grating bound on the substrate for diffracting a light beam in a reflection mode and outputting at least one output light beam, a plurality of nanoparticles being bound on one side of the grating, a molecular recognition unit bound on said nanoparticle surface, and a cover plate covering the nanoparticle-modified side of the substrate. The detecting platform receives a signal while the at least one output light beam passing through the bio-sensing apparatus. The processing unit couples with the detecting platform for receiving and analyzing the signal. Wherein when the analyte passes through the microfludic channel to contact with said nanoparticles, the at least one output light beam changes in accordance with the refractive index of the sample or in accordance with the interaction of the analyte with said molecular recognition unit bound on said nanoparticle surface.
