Abstract:
... Biosensor technology has been extensively investigated for determination of several analytes in clinical diagnosis, food analysis and environmental monitoring. A biosensor includes three parts; a transducer, a bioreceptor (biorecognition element) and a signal processing system. Biorecognition elements are important components of a biosensor because they recognise the target analytes of interest. T ...

... Seed-growth synthesis is a common strategy to prepare silver nanoplates, whose peculiar plasmonic features can be exploited for surface enhanced Raman scattering (SERS) applications. Here we describe the fabrication and characterization of SERS chips using a peculiar in situ seed growth method, yielding a dense layer of nano-objects directly on a glass slide. In this way, geometric features (i.e. ...

The impediment of detection of food contaminants has been overcome by the suspect and non-targeted screening. Still, the results from one laboratory cannot be compared with the results of another laboratory ...
