cfDNA binding and biocompatibility of HPT and ss‐HPT. AFM and DLS results of A) HPT+cfDNA and B) ss‐HPT+cfDNA analyses. Scale bars, 200 nm. cfDNA was incubated with HPT and ss‐HPT at 37 °C for 30 min. C) cfDNA binding efficacy of HPT, ss‐HPT, and P‐G3 with a series of ratios. data indicate the mean ±  S. D. (n = 3). D) Cell viability of HDFs after 24 h of treatment with HPT, ss‐HPT, and P‐G3 at a series of concentrations. Cells without any treatment were used as a negative control. Data indicate the mean ± S. D. (n = 3).
