Nano-copper biomimetic material and preparation method and application of nano-copper biomimetic material

The invention relates to a nano-copper biomimetic material and a preparation method and application of the nano-copper biomimetic material. The nano-copper biomimetic material comprises internal copper nanoparticles and egg white albumin with which the copper nanoparticles are coated, the particle sizes of the copper nanoparticles are 3-9nm, and the mass ratio of the nanoparticles and the egg white albumin is 1: (10-20). The preparation method comprises the following steps that (1) copper (II) sulfate pentahydrate is added into egg white albumin solutions and stirred evenly to obtain a mixed solution; and (2) sodium hydroxide solutions are added into the mixed solution, the pH is adjusted, stirring, dialysis and freeze drying are conducted, then the nano-copper biomimetic material is obtained, and the nano-copper biomimetic material is used in the field of biomedicine. Compared with the prior art, the nano-copper biomimetic material, the preparation method and the application have thebeneficial effects that t
