Morphological changes to MCF-7 cell line after treatment with a control, b only quercetin, c neat AuNPs, d polyethylene glycol 9000 capped Quercetin functionalized AuNPs and e effect of different concentration of Quercetin, AuNPs, and polyethylene glycol 9000 capped and Quercetin functionalized AuNPs on cell viability of MCF-7 cell line. (In d arrows indicate that AuNPs-PG9-QT treated cells were ruptured and observed for irregular shape)
