Abstract:
SERS is becoming an important tool for detection of molecules in ultra-trace level. In this review, an overview of SERS and different types of SERS active substances are presented. The excessive use of metal and/or metal supported nanostructured materials have been used for making the SERS active substances. Along with pure metal nanoparticles, core-shell or hybrid nanoparticles also made their way as SERS active platform. Notably, unusual shapes such as nanostars or nanoplates have used for such purposes. Further, SERS were used for intracellular detection of biomolecules in different types of cells. It is believed that this review would be useful to further development of advanced SERS platform for various applications especially physiological detection of trace molecules.
