The objective of this research is to synthesize gold and silver nanotriangles via green chemistry using plant extracts. The plant extracts will act as the reducing agents and capping agents. By simply altering the reaction conditions (pH of solution, concentration of extract, or temperature of reaction), it should be possible to control the properties of the nanotriangles produced such as size and shape. The optical properties of the synthesized nanotriangles will be measured using UV-visible spectroscopy. It is well known that triangular nanoparticles exhibit two characteristic absorption bands referred to as the transverse (out of plane) and longitudinal (in plane) surface plasmon resonance bands. While the out of plane transverse absorbance more or less coincides with the surface plasmon resonance of spherical gold nanoparticles, the in plane surface plasmon band is a strong function of the edge length of the triangles. Further research will be done on the application of these nanoparticles on the enhanced detection of analytes such as (Rhodamine B and 4-aminothiolphenol) using Raman Spectroscopy.
