Abstract

On the basis of micellar solubilization, a strategy tuning the solubility of gold nanoparticles reversibly was developed. Hydrophobic gold nanoparticles stabilized by octadecylamine (ODA-gold) solubilized in the micellar-like core of poly(vinylpyrrolidone) (PVP) in water to form gold nanoparticles with protective multilayer induced by reduction of interfacial energy. Interestingly, upon redispersing in chloroform, the PVP micellar-like structure can break down and the ODA-gold can be released again. By changing the ratio of PVP/ODA, size-controllable hydrophilic spherical assembly can be prepared. On the basis of the observation of transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR), a reasonable mechanism is interpreted thermodynamically.
