Another successful innovative biosensor with combined microfluidics and biosensing capabilities, furnish real time and automated affinity bioanalysis (e.g. for antigen-antibody assays) through surface plasmon resonance (SPR)-based original optical transduction mechanism. Since molecular recognition trait is central in the biosensing systems, all the structural components can be targeted to device a biosensor for detection of the specific virion particles present in food and environment samples. Molecular nanotechnology-based new nanostructures/nanomaterials such as aptamers are capable for developing highly specific biosensor for target elements detection. DNA-based biosensors have great applications in food and environmental analysis including determination of the pathogenic bacteria , and virus DNA sequence such as that of SARS virus (Abad-Valle et al. Quartz crystal microbalance (QCM)-based piezoelectric sensors can detect the hybridized viral DNA and also the capsid protein-ligand interactions.	./cache/cord-014908-jys1y0k9.txt	./txt/cord-014908-jys1y0k9.txt
