제목 A facile and green functionalization of single-walled carbon nanotubes by polyampholytic polymers for drug delivery application
초록 A novel process for the green chemistry approach of drug nanocarriers using sustainable conditions, and chemical methods involving one-pot synthesis of polymers and surface modification of SWCNTs is reported. Firstly, the polyampholytic alternating polymers were prepared with functional monomers by using thiol-ene chemistry in sustainable conditions. Then, the obtained polymers were applied for a direct functionalization onto the surface of SWCNTs in aqueous media with ultrasonication support through Diels-Alder click reaction. The synthesized hybrid was characterized by TGA, FT-IR, UV-vis, Raman spectroscopy and TEM. These hybrids were used as drug-nanocarriers to improve the drug loading capacity up to 150%. Finally, the in-vitro drug release profiles showed that there was a burst release of DOX at pH 5.5 when compare with the lower release rate at pH 7.4 in the physiological condition.
