The wound sealing and evaluation of the hybrid patch in vitro and in vivo. The hybrid patch with brilliant structural color could effectively seal the perforation with a diameter of 10 mm on the a) porcine intestine and b) rabbit stomach. c) The schematic illustration and photographs of the stomatic perforation, and sealed with suture, fibrin gel, PNH, and hybrid patch. d) The photographs showing the wound area 7 days (i: suture, ii: fibrin gel, iii: PNH, v: hybrid patch) and 3 days (iv: hybrid patch) after the operation. e) The blood routine examination of the blood from the normal rats (control), rats sealed with suture, fibrin gel, PNH, and hybrid patch (n = 3, biologically independent samples). Data are showed as mean ± SD.
