Abstract : The interaction of citrate- and polyethylene imine (PEI)-functionalised gold nanoparticles (GNP) with cancer cell lines with respect to the cellular response was studied. It was found that GNP/citrate nanoparticles were able to induce apoptosis in human carcinoma lung cell lines A549, but GNP/PEI did not show any reduction in the viability of the cells in human breast cancer cell line MCF-7 and A549 cell lines. FACS data confirmed that the number of apoptotic cells increased with increase in the concentration of GNP/citrate nanoparticles. Decline in cellular expansion and changes in the nuclear morphology were noted after the treatment of GNP/citrate nanoparticles on A549 cell lines, which itself is a direct response for stress induction. The induction of cellular apoptosis was further confirmed by DNA fragmentation assay. These data confirm the potential of GNP/citrate nanoparticle to evoke cell-specific death response in the A549 cell lines. © 2013 Taylor Francis.
