An experimental research on pH-responsive amino acid-coated Ni(1−x)CoxFe2O4 nanoparticles as a nano-carrier for drug delivery and biological applications

Methionine-coated Ni(1−x)CoxFe2O4 nanoparticles could be an ideal candidate for drug delivery due to its drug loading capacity and its high biocompatibility. In the present study, the amount of Tetracycline loading was 0.33 mg in 1 mg of carrier. The in vitro release studies demonstrated a gradual drug release up to 120 h. The drug release at pH-5 (71.01%) was higher than pH-7.4 (19.56%). It was efficiently loaded on the carrier and tested on...
