A facile approach for the synthesis of chitosan-based Au nanostructures that have interesting absorptions in the near-infrared (NIR) region is presented. The effects of cooling treatment and the cross-linking agent glutaraldehyde on the formation of Au nanostructures based on chitosan were investigated. It has been demonstrated that the size and shape, and thus the optical properties of Au nanostructures, could be modulated via cooling treatment. The optical absorption extension of these Au nanostructures in the NIR region is promising in biomedical applications. The presence of a cross-linking agent, glutaraldehyde, during synthesis accelerated the reduction of the Au precursor and favored the growth of isotropic Au nanoparticles. A possible mechanism for the change in growth modality of Au nanostructures with and without glutaraldehyde was elucidated.
