Recent advances in polymeric electrospun nanofibers for drug delivery.

Electrospinning is a simple unit operation process by which polymeric nanofibers with diameters ranging from a few nanometers to hundreds of micrometers can be fabricated using an electrostatically operated jet of polymer solution or polymer melt. Nanofibers because of their interesting features, such as surface-to-volume ratio, high surface area, microporosity, and nonwoven structure, provide numerous opportunities to design novel carrier systems for large commodities of therapeutics. Physicochemical properties of nanofibers depend on several process and formulation parameters, such as applied voltage, flow rate, polymer selection, and concentration of polymer used.

Transmucosal delivery of Docetaxel by mucoadhesive polymeric nanofibers.

The aim of the present study is to design a mucoadhesive nano-carrier system which retains at the site of application and maximizes the therapeutic potential of anticancer drug as well as reduces their systemic side effects. In the present study PVA nanofibers of Docetaxel were prepared using electrospinning machine. The resulting nanofibers were characterized through various parameters such as surface morphology, drug loading, in-vitro drug release, tensile strength, mucoadhesiveness, drug permeability, degree of swelling and anticancer activities against selective cell lines to establish their therapeutics potential.
