Gold nanoparticles (NPs) show great potential as photothermal therapy agents because of their unique capability to convert a suitable (resonant) external light to heat. Usually NPs are stabilized by means of cationic surfactants (e.g. CTAB) which, in their turn, exhibit a very high intrinsic toxicity. The possibility to detoxify NPs by using bio-inspired materials such as proteins is of great interest. In this framework, we have synthetized and characterized a water dispersion of spherical, keratin-capped, NPs. We report a detailed photo-thermal characterization realized by means of a high resolution thermal camera. Results represent a new avenue in the field of high precision, minimally invasive, biomedical applications.
