Abstract

The aspect ratio of Au nanorods can be precisely engineered using near-infrared nanosecond-pulsed laser irradiation, which enables ultrafast, confined energy deposition inaccessible under continuous-wave irradiation. In this study, we demonstrate a novel method for reshaping Au nanorods encapsulated within thin (
