A new approach to engineer a local drug delivery system with delayed release using nanostructured surface with nanotube arrays is presented. TNT arrays electrochemically generated on a titanium surface are used as a model substrate. Polymer micelles as drug carriers encapsulated with drug are loaded at the bottom of the TNT structure and their delayed release is obtained by loading blank micelles...
The use of porous silica microshells (microparticles) generated from fossilised diatoms known as diatomite or diatomaceous earth (DE) as a natural drug carrier for drug delivery application is presented. The structure, morphology, particle size distribution, porosity, surface area and crystallinity of diatom microshells obtained from Australian mine (Mount Sylvia Diatomite Pty. Ltd.) were characterised...
