Serum binding studies. (A) Ultraviolet–visible spectra of folic acid–curcumin–gold–polyvinylpyrrolidone nanoconjugates (FA–CurAu-PVP NCs) before and after incubation with human serum and (B) Fourier transform infrared spectra of naive human serum and FA–CurAu-PVP NCs before and after incubation with human serum. (C) Zeta potential measurements of FA–CurAu-PVP NCs before and after incubation with human serum. (D) Dynamic light scattering measurements of FA–CurAu-PVP NCs before and after incubation with human serum.
