Paclitaxel (PTX) is one of the most effective drugs in the treatment of cancer. However, its usability is limited due
to low solubility and side effects. In this study, we investigated anticancer effects of PTX bonded silver nano particles (AgNPs-PTX) on 4 different cancer cells, namely MDA-MB-231, MCF-7, 4T1, Saos-2, and on non cancerous HUVEC cells. The silver nanoparticles (AgNPs) that we synthesized were first characterized by UV VIS, FTIR, SEM, and DLS analysis. The size of AgNPs was measured to be around 3 nm and AgNPs-PTX
around 10 nm. AgNPs-PTX were found to be 2 to 10 times more effective than PTX alone. Especially, Saos-2
cells were found to be approximately 10 times more sensitive to AgNPs-PTX than PTX alone. AgNPs-PTX did not
caused toxicity on non-cancerous HUVEC cell and significantly reduced the viability of all cancer cells we tested.
Our findings suggest that AgNPs-PTX may be an anticancer agent candidate that is more effective than PTX
alone and specific to Saos-2 cells.
