(a) ¹H-NMR spectra of PC₄ nanoassembly measured in D₂O at pH 7.4, pH 6.5, and pH 5.5, respectively. (b) Relative peak intensity of curcumin in the nanoassembly measured in D₂O at pH 5.5, pH 6.5, and pH 7.4, respectively. (c) pH-sensitive membrane-lytic activity of CCM nanoassemblies after 2 h of incubation with seep erythrocyte at pH 5.5, pH 6.5, and pH 7.4, respectively. Values are average of three separate experiments in triplicate and are expressed as mean ± SD.
