Abstract

A novel aggregate of gold nanorods (NRs) and myoglobin (Mb) was successfully fabricated by electrostatic interactions between the NR and Mb using positively charged biocompatible NRs. The aggregation induced some deformation of Mb, as was evaluated from circular dichroism measurements. Pulsed 1064nm laser irradiation to the aggregate has released some of the Mb proteins from the aggregate that resulted in the concomitant reshaping of the gold NRs in the aggregate. Some deformations of Mb were observed resulting from aggregation and subsequent laser irradiation.
