Abstract

Abstract: Gold nanorods have received more and more attention due to their unique optical and electronic properties. In particular, the tunable surface plasmon resonance characteristics of gold nanorods allow them to gain wide applications in bio-labeling, imaging, bioanalysis, biomedicine, etc. This review discussed the optical properties of gold nanorods and several surface modification methods, and summarized the applications of gold nanorods in the fields of biological molecular probe, fluorescent probe, cancer diagnosis and photothermal therapy. The main issues on gold nanorods and their applications in biology are also discussed.

Key words: gold nanorods, synthetic methods, optical properties, surface modification, biological applications
