摘要:
50-nm diameter halloysite clay nanotubules with 15 nm lumen were used for loading poorly soluble drugs and sustaining their release. Loading was optimized by varying pH and alcohol/ water ratio in the solvent with a maximum drug loading of 12 volume%. Near linear release of Dexamethasone, Furosemide, and Nifedipine was demonstrated for 5-10 hours. Its capacity for the time release of drugs, along with its simple loading procedure and the biocompatibility of halloysite nanotubules makes this method a prospective drug delivery system.
