Recent advances of nanostructure implemented spectroscopic sensors—A brief overview

Abstract

By the conjugation of requirements of high-performance sensing platforms and developments of nanotechnology, various nanostructure implemented photonic, spectroscopic sensors have been investigated. In this review article, we address 3 types of nanostructure implemented optical sensor techniques—localized surface plasmon resonance (LSPR) sensors, extraordinary optical transmission (EOT) based sensors, and Raman-based spectroscopic sensors—and recent advances of the nanostructure assisted sensors arranged by 2 important issues: the employment of novel nanostructures and the application of newly investigated fabrication techniques for larger sensing area.
