Laser generated gold nanocorals with broadband plasmon absorption for photothermal applications

Gold nanocorals (AuNC) are obtained by a “green” method consisting of laser irradiation, followed by anisotropic self-assembly without templating agents. The AuNC dispersion has broadband plasmon absorption from the visible to near infrared region, unitary light-to-heat conversion efficiency, versatile surface chemistry and biocompatibility.
