Surface Enhanced Raman Spectroscopy (SERS) is a surface technique that is capable of increasing the Raman signal of a sample by several orders of magnitude.  Analyte molecules are adsorbed onto a roughened metal surface or onto metal nanoparticles. The size and shape of nanoparticles greatly affect the degree of signal enhancement. This investigation involves the production of silver and gold nanoparticles by several methods and comparison of the SERS enhancement associated with each method. In addition, the enhancement due to the bonding of several amines including pyridine to the nanoparticles will be investigated. The results are expected to demonstrate that gold and silver nanoparticles fabricated by different methods are useful to carrying out SERS-based studies and could lead to development of micro sensors. <br/>
