Optical fiber biosensors nanoparticles

The representative techniques currently applied for an efficient, specific, rapid detection of viruses are described by Cay gill et al. Among them, electrochemical biosensors based on amperometric, potentiometric, and impedance measurements, optical biosensors that use surface plasmon resonance, optical fibers and piezoelectric biosensors based on microcantilevers, and recently the use of nanoparticles and novel nanomaterials as alternate recognition surfaces have been widely applied.
