Quantitative evaluation of the SUP glues in ex vivo and in vivo applications. A–B) The underwater adhesion test and adhesion energy of SUP adhesive on steel and glass, respectively. C) The ex vivo application of SUP glue on porcine skin and muscle. Three parallel experiments were performed for each group of specimens. D) Schematic illustration of the in vivo hemostasis model, that is, use of SUP glue on pig liver and kidney. The blue box indicates the pasting position on pig organs. E) The bleeding wound was ceased in 10 s after SUP glue was applied. The scale bar is 0.5 cm.
