Plasmonic Materials In Nano Scales Exhibits Tremendous Properties Due To Their Modified Boundary Conditions. Consequently Nano-materials Exhibit Localized Surface Plasmon Resonances And Propagating Surface Plasmons. Excitation Of These Surface Plasmon Resonance Modes Generates Evanescent Fields In The Very Neighborhood Of Plasmonic Nano-particles/nano-structures.plasmonic Nano-particles/nano-structures Facilitates. The Raman Signatures Enhancements From The Analyte Molecules Adsorbed On Them. Nano Platforms Can Talk To Molecules And Their Discussion Can Be Decoded Through Surface Enhanced Raman Spectroscopy.
