This study evaluates the use of nanotubes (NTs) as a matrix for local drug delivery modified by a biodegradable polymeric coating on medical-grade nitinol (NiTi alloy) surfaces. For this purpose, NiTi was anodized within parameters that promote the formation of NTs, ultrasonicated, annealed and impregnated with vancomycin hydrochloride. To improve bioperformance, poly(lactic-co-glycolic acid) (PLGA) was also deposited on the drug-loaded NTs. The samples were characterized in terms of structure, wettability, drug delivery, corrosion and cytocompatibility. Scanning electron microscopy and water contact angle measurements signify the formation of open-top homogeneous NTs of 600– 700 nm in length and ~30 nm in …

The advent of porous materials, in particular zeolitic nanoparticles, has opened up unprecedented putative research avenues in nanomedicine. Zeolites with intracrystal mesopores are low framework density aluminosilicates possessing a regular porous structure along with intricate channels. Their unique physiochemical as well as physiological parameters necessitate a comprehensive overview on their classifications, fabrication platforms, cellular/macromolecular interactions, and eventually their prospective biomedical applications through illustrating the challenges and opportunities in different integrative medical and pharmaceutical fields. More particularly, an update on recent advances in zeolite-accommodated drug delivery and the prevalent challenges regarding these molecular sieves is to be presented. In conclusion, strategies …
