摘要: Embodiments of the present disclosure provide an injectable photothermal hydrogel based on melanin and a preparation method and an application thereof. The injectable photothermal hydrogel is a hydroxypropyl chitosan/bis-amino polyethylene glycol modified melanin nanoparticles (HPCS/MP) hydrogel. The HPCS/MP hydrogel is prepared by mixing bis-amino polyethylene glycol modified melanin nanoparticles (MP) with hydroxypropyl chitosan (HPCS). The MP is synthesized by an amidation reaction of the melanin and the bis-amino PEG. A ratio of a volume of an MP solution to a volume of an HPCS solution in the HPCS/MP hydrogel is 4:6. A concentration of the MP solution is 20 wt %. A concentration of the HPCS solution is 4 wt %.
