itionally, GO can be used as photothermal agent (generation of heat by NIR irradiation) or photodynamic therapy (using visible light irradiation) inactivating the capsids by local thermal shock or by radical formation during irradiation, respectively. The use of phototherapies may significantly augment the antiviral properties of the materials. However, we must keep in mind that these therapeutic modalities can be applied only to disinfection, since the radical/heat production may be harmful for the healthy tissues in vivo. Photodynamic t
