Abstract

Pulsed-laser irradiation induced release of modified PEG chains on gold nanorods. A maximum release efficiency of 65% is obtained. The efficient release was occurred by combination of cleavage of Au-S bonds, the fragmentation of PEG chains, and the decrease of the surface area. CW-laser irradiation did not release any PEG chains; however, it was effective to increase temperature of the nanorod solution.
