Cytotoxicity evaluation of the NPs with different concentrations plain vs. loaded (A) Results of cell viability after soluble and encapsulated PHMB treatment of human dermal fibroblasts (HDFs). Data all n = 6, mean ± S.D. Asterisks denote significance as determined by pairwise t-tests with ** p = 0.01, *** p < 0.001 and **** p <0.0001 . (B) Morphological changes of HDF cells after soluble/encapsulated PHMB exposure for 24 h (scale bars = 50 μm). NT indicates the no-treatment media only control group.
