Scheme of the A) oxidation reaction of alginate‐dopamine (ALG‐DA) pill on different parts of gastrointestinal (GI) tract B) ALG‐DA adhesive hydrogel formation on tissue. C) The photographs of ALG‐DA pills gelation on different parts of GI tract of pigs in vitro at different time‐points. D) The gelation degree calculation of ALG‐DA pills on different parts of GI tract of pigs in vitro. Data is represented as mean ± S.D., n = 3, *indicates p < 0.05.
