Abstract Rapid synthesis of mono-dispersed gold nanoparticles through economically feasible green chemistry approach is highly desirable. In this study, we have developed a method to synthesize mono-dispersed gold nanoparticles (PAuNPs) by mixing gold solution with fruit peel extract of Punica granutum without using any surfactant or external energy. In this method, physiologically stable, biocompatible PAuNPs were formed within 60s. Casein, being a biocompatible polymer, is used to couple the prepared PAuNPs for functionalization of folic acid, which is highly expressed in cancer cells. These functionalized PAuNPs could be used for targeted drug delivery for cancer with enhanced therapeutic efficacy and minimal side effects. PAuNPs were characterized by UV, IR, TEM, Particle size analyzer and zeta potential measurement. In vitro stability of the PAuNPs was also analyzed. Hemocompatibility of PAuNPs was evaluated in human blood samples and found that the particles were hemocompatible. The toxicity of the PAuNPs, 5-Fu and [email protected] was analyzed in zebrafish embryos. The in vitro cytotoxicity of free 5-Fu, [email protected] was investigated against MCF-7 cells (breast cancer) and observed that the amount of 5-Fu required to achieve 50\% of growth of inhibition (Ic50) was much lower when compared to free 5-Fu.
