SERS Sensor Applications in Environmental Analysis and Biotechnology

Surface Enhanced Raman Spectroscopy (SERS) takes the advantages of strongly increased signal of Raman scattering generated by local field enhancements near metallic nanostructures. The internal modes of the reporter molecule can be used for monitoring the signal, and appropriate placement of the reporter molecule on the metal nanoparticle surface is a well-appreciated challenge. Several approaches have been suggested for this purpose, and multipurpose functionalized hybrid nanoparticles are very promising for the detection of trace amounts of analyte. Simple and fast generation of nanoparticles and their modification with appropriate probe pave the way for new SERS applications.
