| Abstract |
To visualize the bio-molecular interaction at a single molecular level in live cells, the development of imaging probe is essential. Gold nanoparticles (Au NPs) have unique optical properties due to the localized surface plasmon resonance (LSPR) and it is well known as an imaging probe in live cells because of their non-toxicity and chemical stabilities. Especially, gold nanorods (Au NRs) have the interesting optical properties depending on aligned directions. Therefore, we analyzed the optical properties of Au NRs using polarized dark-field scattering microscopy. When changing rotation degrees of polarized light, intensity changes were observed. Then we confirmed the availability of Au NRs as a plasmonic probe simultaneously visualizing lateral and rotational molecular dynamics in cells. |
