Material and Design Toolkit for Drug Delivery: State of the Art, Trends, and Challenges

“…Over the last two decades, numerous CD-based ocular drug delivery methods have been developed . Teng et al studied cationic β-CD derivatives to solve the metformin hydrochloride degradation problem before reaching the intestine . It was later discovered that the produced nanoparticles could be deconstructed by increasing pH and reassembling by lowering pH to the starting point.…”
