The synthesis of multifunctional nanoparticles conjugated with anti-Her2 affibody and monomethylauristatin E

Conjugation of bioactive xenobiotics with innert particles often improves their efficacy and/or specificity. In this work we designed superparamagnetic ferric oxide nanoparticles (NPs) conjugated with a strong cytotoxic drug, monomethylauristatin E (MMAE), and evaluated their potential against cancer cells. Cytotoxicity tests showed that the conjugate was at least twice as toxic as the free drug. We then studied the cytotoxic potential of the...
