Halloysite nanotubes-polymeric nanocomposites: characteristics, modifications and controlled drug delivery approaches

Mucoadhesion : a New Polymeric Controlled Drug Delivery

Since last three decades delivery of the desired drug as muocoadhesive drug delivery systems has been subject of interest. Mucoadhesion involving a polymeric drug delivery system is a complex phenomenon that includes theory of diffusion, wetting, adsorption, fracture and interpenetration of polymer chains amongst various other processes. Various polymer-based properties such as the degree of cr...

Electrospun polymeric nanofibers for transdermal drug delivery

Conventional transdermal drug delivery systems (TDDS) have been designed for drug delivery through the skin. These systems use the permeability property of stratum corneum, the outermost surface layer of the skin. Applying polymeric micro and nanofibers in drug delivery has recently attracted great attention and the electrospinning technique is the preferred method for polymeric micro-nanofiber...

Controlled Drug Delivery Approaches for Rheumatoid Arthritis

A cure for rheumatoid arthritis is yet to be discovered. Although vast resources have been expended in the search for an immunological key to switch off the rheumatoid process, the most significant advances in the treatment of rheumatoid arthritis in recent times had come from gaining better understanding and skill in the safe use of existing disease modifying antirheumatic drugs (DMARDs). If p...

Halloysite Nanotubes: Controlled Access and Release by Smart Gates

Hollow halloysite nanotubes have been used as nanocontainers for loading and for the triggered release of calcium hydroxide for paper preservation. A strategy for placing end-stoppers into the tubular nanocontainer is proposed and the sustained release from the cavity is reported. The incorporation of Ca(OH)₂ into the nanotube lumen, as demonstrated using transmission electron microscopy (TEM) ...
