摘要：

A pH and magnetically dual responsive platform was synthesized by PEGylation of poly (ethylenimine) dendrimers grafted magnetic nanoparticles for targeted cytarabine delivery. Characterization techniques confirmed the platform structure and properties. Optimal drug adsorption occurred at pH 8, with an adsorbent dosage of 0.01 g, and 60 min of contact time at 298 K. Pseudo-second-order kinetic and Langmuir isotherm models best fit the adsorption data. The thermodynamic data shows that drug adsorption is a favorable and spontaneous process. Drug release rates were 61.45 % and 21.92 % at pH 5.6 and 7.4 over 6 h. The release kinetics followed Korsmeyer-Peppas model, showing non-Fickian behavior.
