Physical Characterization and Biodistribution of Cisplatin Loaded in Surfactant Modified-Hybrid Nanoparticles Using Polyethylene Oxide-b-Polymethacrylic Acid
Purpose: Conjugating cisplatin into hybrid nanoparticles is intended to enhance tumor accumulation in cancer therapy due to drug interaction with polymer and prevent premature drug release because of the presence of a lipid layer. Methods: Hybrid nanoparticles composed of polyethylene oxide-b-pol...

| Summary: | Purpose: Conjugating cisplatin into hybrid nanoparticles is intended to enhance tumor accumulation in cancer therapy due to drug interaction with polymer and prevent premature drug release because of the presence of a lipid layer.
Methods: Hybrid nanoparticles composed of polyethylene oxide-b-polymethacrylic acid, egg phosphatidylcholine, and surfactant, i.e. sodium cholate/sodium deoxycholate/Tween 80, were prepared by the injection method. Cisplatin was subsequently loaded by incubating the polymer-drug mixtures at the molar ratio of carboxylate ions of 2:1.
Results: The results showed that the addition of surfactants produced particle sizes between 33 and 52 nm. The addition of cisplatin increased the ζ-potential to slightly positive charges with encapsulation efficiencies of 5%-18%. An in vivo biodistribution study of mice identified a cisplatin plasma concentration of sodium cholate-modified hybrid nanoparticles 10 times higher than cisplatin solution, thus producing high tumor accumulation.
Conclusion: Conjugating cisplatin into sodium cholate-modified hybrid nanoparticles improves its accumulation in tumors. |
