Plasmonic silver nanospheres embedded ε-caprolactone/reduced graphite oxide nanolayers as active SERS substrates.

Label-free, sensitive, compatible and non-invasive nature of surface enhanced Raman spectroscopy (SERS) had substantially influenced various biological applications such as cell investigations, analysis of biomolecules such as DNA, RNA, proteins and detection of biomarkers for various diseases. This renders the engineering of bio-compatible, sensitive and efficient SERS substrates a necessity. In this study, the SERS activity of plasmonic silver nanospheres embedded ε-caprolactone/reduced graphite oxide nano layers (AGP) has been analyzed.
