Synthesis and surface modification of metallic nanoparticles: Sensitivity, influence of shape, concentration and excitation wavelength on chemical detection by Sers
Surface-Enhanced Raman Spectroscopy (SERS) is a powerful spectroscopic technique that can be used for detecting analytes at very low concentrations. In SERS, the intensity of vibrational signatures can be enhanced by factors ...
Synthesis and characterization of copper nanoparticles: Architectural morphologies and applications in surface enhanced raman spectroscopy
The preparation of copper colloidal suspensions was conducted by three different methods. These methods used wet chemical synthesis, in which a metal salt solution was mixed with a solution containing the reducing agent. ...
