Cytotoxicity studies assayed by the MTT method.

Notes: (A) The influence of HCPT, different-sized PSH-AuNPs, and HCPT-AuNPs on the survival of MDA-MB-231 cells (HCPT concentration 50 μg/mL). (B) Cytotoxicity studies of different concentrations of HCPT-AuNPs and HCPT on MDA-MB-231 cells. The results are expressed as mean ± SD. HCPT-AuNPs-10, 25 and 50: HCPT-AuNPs of an average diameter of 10, 25 and 50 nm.

Abbreviations: MTT, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide; HCPT, 10-hydroxycamptothecin; PSH, α-methoxy-poly (ethylene glycol)-ω-mercapto; AuNPs, gold nanoparticles; SD, standard deviation.
