Multifunctional nanoparticles have high potential as targeting delivery vehicles for cancer chemotherapy. In this study, silver-decorated gold nanorods (AuNR\Ag) have been successfully used to deliver specific, targeted chemotherapy against breast cancer (MCF7) and prostate carcinoma (PC3) cell lines. Doxorubicin, a commonly used chemotherapy, and anti-Epithelial cell adhesion molecule (anti-EpCAM) antibodies were covalently bonded to thiolated polyethylene glycol-coated AuNR\Ag, and the resultant system was used to deliver the drugs to cancer cells in vitro. Furthermore, these nanoparticles have a unique spectral signature by surface enhanced Raman spectroscopy (SERS), which enables reliable detection and monitoring of the distribution of these chemotherapy constructs inside cells. The development of interest in a plasmonic nano drugs system with unique spectroscopic signatures could result in a clinical approach to the precise targeting and visualization of cells and solid tumors while delivering molecules for the enhanced treatment of cancerous tumors.
