Characterizations of gold nanoparticles (AuNPs) and AuNP-encapsulated human serum albumin nanoparticles (Au@HSANPs). (A) The maximum absorption peak of AuNPs prepared by Turkevich’s method was at 525 nm; (B) the AuNPs exhibited a monodisperse structure and the average particle size was 22.5 ± 5.9 nm; (C,D) size distribution and TEM images. The hydrodynamic diameter of Au@HSANPs was 213.3 ± 32.9 nm determined by DLS; (E) the stability of Au@HSANPs represented by the change of particle size and PDI after incubation in deionized water at 4 °C for 22 days.
