a Swelling behavior of PolyLA-Na/PolyLA adhesive patches with different compositions in artificial saliva (n = 3); b Monomer release ratio of PolyLA-Na/PolyLA adhesive patches with different compositions in artificial saliva for different times (n = 3); c FT-IR spectra of PolyLA-Na/PolyLA adhesive patch before and after monomer release; d Scavenging effect of PolyLA-Na/PolyLA adhesive patches on OH· radicals at 0.5 h (n = 3); e ABTS radical clearance ratio of PolyLA-Na/PolyLA adhesive patches determined at different times (n = 3, ***p < 0.001); f Digital images displaying minimum inhibitory concentration of the PolyLA-Na/PolyLA adhesive patches against E.coli and S.aureus; g, h Sterilization rate of PolyLA-Na/PolyLA adhesive patches with different concentrations against E.coli and S.aureus at different times (n = 3). (All presented data are mean values ± SD from the mean from n = 3 independent measurements on independent samples. All p values were calculated using a two-sided Student’s t test).
