The effectiveness of the Au NPs and Au NPs-PEG to MCF-7 (a cell line from human breast cancer) was estimated using antioxidant activity and clonogenicity assays. The results showed that the produced nanoparticles were generally sphere-shaped with a smooth surface, with sizes of about 20.57 ± 2.51 nm and 29.14 ± 3.31 nm for gold nanoparticles and gold nanoparticles -PEG conjugate, respectively. Investigations were conducted into the antioxidant capacity of Au NPs and Au NPs-PEG conjugate against DPPH, and the Au NPs-PEG conjugate showed the maximum radical scavenging (84.661.79%) in concentration-dependent increments. A clonogenic survival assay investigated Au NPs and Au NPs-PEG conjugates for cytotoxicity against the MCF-7 cell line. Au NPs conjugate lowered the number of MCF-7 clones more effectively than the control. The generated Au NPs-PEG had a strong cytotoxic effect on the MCF-7 cells, accelerating cell death and enhancing cellular absorption of the chemical. |
