MNPs surface charge and schematic of MNPs-drug interaction (A) Zeta potential of MNPs at different pH shows that the physiological pH 7.4 generates significant negative charges on its surface. (B) Schematic illustration showing interaction between negative charge on MNPs surface and positive charge on selected moieties (NH2, CH3, etc.) of CTOP peptide at pH 7.4.
