Polymer decorated gold nanoparticles in nanomedicine conjugates

Schematic illustration of the targeted cancer cell death upon treatment of the guava leaf extracts immobilized gold nanoparticles (AuNP-Gua). AuNP@PEG-water-soluble flavonoids conjugates for “natural drug” delivery. Observed results show that the cell uptake of “natural drug” was enhanced by the AuNP@PEG conjugates, and the cytotoxicity of this delivery system is significantly enhanced compared with classical approach.155
