Breast cancer due to its high incidence and mortality is the second leading cause of death among females. On the otherhand, nanoparticle-based drug delivery is one of the most promising approaches in cancer therapy, nowadays. Hence, margetuximab-and polyethylene glycol-conjugated PAMAM G4 dendrimers were efficiently synthesized for targeted deliveryof quercetin (therapeutic agent) to MDA-MB-231 breast cancer cells. Synthesized nano-complexes were characterized usinganalytical devices such as FT-IR, TGA, DLS, Zeta potential analyzer, and TEM. The size less than 40 nm, – 18.8 mV surfacecharge, efficient drug loading capacity (21.48%), and controlled drug release (about 45% of drug release normal pH after 8 h)were determined for the nano-complex. In the biomedical test, the cell viability was obtained 14.67% at 24 h of post-treatmentfor 800 nM concentration, and IC50was ascertained at 100 nM for the nano-complex. The expression of apoptotic Bax andCaspase9 genes was increased by more than eightfolds and more than fivefolds after treatment with an optimal concentrationof nanocarrier. Also, more than threefolds of cell cycle arrest was observed at the optimal concentration synthetics, and 27.5%breast cancer cell apoptosis was detected after treatment with 100 nM nano-complex. These outputs have been indicatingthe potential capacity of synthesized nano-complex in inhibiting the growth of breast cancer cells.
