Photochemical and analytical applications of gold nanoparticles and nanorods utilizing surface plasmon resonance

In recent years, plasmonics has emerged as a promising tool in the fields of analytical chemistry and biochemistry. In particular, surface plasmon resonance at the surfaces of gold nanostructures has led to the development of widespread interest in gold nanoparticles. In this review, we describe some of the recent progress in the manufacture and use of gold nanoparticles, with particular emphasis on gold nanorods. Furthermore, the spectroscopic and photochemical applications of gold nanospheres and nanorods are described.
