Micro-and Nanoelectromechanical Biosensors (eBook, ePUB)

• Format: ePub

Produktbeschreibung

Most books dedicated to the issues of bio-sensing are organized by the well-known scheme of a biosensor. In this book, the authors have deliberately decided to break away from the conventional way of treating biosensing research by uniquely addressing biomolecule immobilization methods on a solid surface, fluidics issues and biosensing-related transduction techniques, rather than focusing simply on the biosensor. The aim is to provide a contemporary snapshot of the biosensing landscape without neglecting the seminal references or products where needed, following the downscaling (from the micro- to the nanoscale) of biosensors and their respective best known applications. To conclude, a brief overview of the most popularized nanodevices applied to biology is given, before comparing biosensor criteria in terms of targeted applications.
