Abstract: A hydrogel nanocomposite based acne treatment patch loaded with doxycycline and a method of developing thereof is described herein. The present invention relates to the preparation of biocompatible hydrogel matrix comprising polyvinyl alcohol, linseed mucilage extract, nano zinc-oxide crosslinked dually via covalent linkages and free radical polymerization by electronic beam exposure. The pore size of the hydrogel acne patch ranges between 0.1-0.5 ?m. The doxycycline loaded acne patches were able to inhibit the growth of S. aureus in an in-vitro bacterial growth inhibition assay.

Abstract: Chronic wounds are medical care concern and severe clinical challenge worldwide. A nanofiber based new wound dressing scaffold and a method of developing thereof for treating diabetic wounds is described here. More specifically, the present invention relates to the preparation of biocompatible Polyacrylonitrile (PAN) nanofiber scaffold comprising of Quercetin, Zinc oxide and polyacrylonitrile by electrospinning. The nanofibers formed has the average diameter of approximately 160 nm and show excellent antibacterial and wound healing potentials.

Abstract: This invention demonstrates that silver nanoparticles can be synthesized by reducing silver nitrate with sodium borohydride in a presence of surface stabilizer polystyrene-block-poly(2-vinyl pyridine) in order to overcome the aggregation of silver nanoparticles.

Abstract: A drug delivery system comprising the synthesis of resorcinarene based novel amphiphilic supramolecular macrocycle that is capable of self-assembling in nano-scale vesicles upon its contact with aqueous medium and its use as nano-drug loading vehicle when mixed with cholesterol (2:1 ratio w/w).
