Abstract

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.

Rapid and sensitive detection of trace amounts of analyte remain a challenge in numerous areas such as food industry, medical diagnosis, biodefence, and drug analysis. This chapter underlines the SERS-based, fast, sensitive, and selective biosensor applications regarding the most preferred surface preparation techniques. The latest labeled and label-free applications of Raman spectroscopy in biology and especially recent contributions to the biosensors are the main topics of this chapter. In addition, optimization strategies and the analytical performance of the SERS-based assays are presented in the scope of this chapter.
