Abstract

In this study, three-dimensional (3D) crosslinked bovine serum albumin (BSA) microstructures containing gold nanorods (AuNRs) at different absorption wavelengths were fabricated via multiphoton excited photochemistry using rose Bengal (RB) as the photoactivator. After the processing, a higher laser power, greater than the threshold of the AuNR photothermal damage at the matched wavelength for the longitudinal plasmon resonance of AuNR, is adopted to reshape the AuNRs into gold nanospheres at the designed positions of the 3D structure. As a result, 3D BSA microstructures containing different color AuNRs at the designed positions can be successfully fabricated. The AuNRs-doped BSA multicolor microstructures not only can be applied in biomedical scaffolds with plasmonic properties such as two-photon luminescence imaging and photothermal therapy but also can be a specific 3D biomaterial microdevice for plasmonic field.
