Fig. 4.

(A) Representative optical images of colony-forming units for MRSA and E. coli suspensions. (B) Fluorescence micrographs for the membrane permeability of MRSA cultured with hydrogel. Hoechst 33342 staining, blue channel; PI staining, red channel. (C and D) The concentration of K+ (C) and β-galactosidase (D) in the culture medium of MRSA treated with GM-P@HA-P hydrogel. (E and F) Representative fluorescence and SEM images of live/dead staining assay of the MRSA biofilm treated with hydrogel. Data are shown as means ± SDs, n = 3. *P < 0.05.
