New diffusion reflection imaging system using gold nanorods coated with poly-(3,4-ethylenedioxythiophene)

In this study we developed a new method for coating gold nanorods (GNRs) with poly-(3,4-ethylenedioxythiophene) (PEDOT). The optical properties of this new composite were tested by Monte Carlo (MC) simulation and diffusion reflection (DR), showing a unique surface plasmon resonance (SPR) and a more obvious change in the reflected light intensity. Our results indicate that this composite has great potential as a contrast agent for molecular imaging in biomedical applications. (C) 2016 Optical Society of America
