1. A gene editing nanocapsule, comprising an inner core and an outer shell encapsulating the inner core, wherein the inner core comprises a Cas/sgRNA ribonucleoprotein complex obtained by combining Cas nuclease and sgRNA, wherein the Cas nuclease is Cas9 nuclease, and a molar ratio of the Cas nuclease and the sqRNA is 1:1.2; and the outer shell comprises a polymer polymerized by a monomer material, wherein the monomer material comprises a first monomer and a second monomer that can be polymerized capable of polymerizing with each other, wherein the first monomer is guanidino acrylate and the second monomer is N,N′-bis(acryloyl)cystamine, and a molar ratio of the Cas nuclease and the guanidino acrylate is 1:200-250.
