What is Plasmonic Sensors

Chapter 13
Advances in MEMS and Microfluidic Systems
Biosensors known as plasmonic sensors use the plasmonics principles to track changes in a sample's refractive index. Plasmon resonance happens when light energy is absorbed by metal nanoparticles, producing oscillations of the conduction electrons at the metal's surface. Plasmonics is the study of the interaction between light and metal surfaces.

Abstract
The unexpected increase of the global SARS-CoV-2 or COVID-19 pandemic in early 2020 has required exceptional methods to accomplish instant detection and decrease the spread rate. This chapter highlights the advance of lab-on-chip biosensing devices for the identification of COVID-19 infection. In this chapter, the authors study the roles of using lab-on-chip equipment in response to the present global COVID-19 pandemic, comprising their potential for rapid sample-to-answer processing times and facility of incorporation into a variety of healthcare backgrounds.
