Collagen, a fibrous structural protein, is a major component of skin, tendon, bone, and other connective tissues. Collagen is one of the dominant biomaterials used for tissue engineering and drug delivery applications. 2,2,2-Trifluoroethanol (TFE) has been used as a co-solvent in the preparation of collagen based biomaterials, which are used for tissue(More)
Quercetin had been shown to be effective in the management of arthritis. However, bioavailability of quercetin is a concern for such treatment. This work aims at the development of intra-articular drug delivery system by controlled release of quercetin (loaded in microspheres) for the management of rheumatoid arthritis. Polycaprolactone has been used for(More)
Arthritic diseases, such as osteoarthritis and rheumatoid arthritis, inflict an enormous health care burden on society. Osteoarthritis, a degenerative joint disease with high prevalence among older people, and rheumatoid arthritis, an autoimmune inflammatory disease, both lead to irreversible structural and functional damage to articular cartilage. The aim(More)
A biodurable porous scaffold of collagen with good biocompatibility and enhanced wound healing potential is prepared through casting technique using tannic acid (TA) as crosslinker. The morphological analysis of the tannic acid cross-linked collagen scaffold (TCCs) distinctively shows scaly interlinks with large pores. The enzymatic stability of the(More)
We recently experimented with collagen coating on the surface of quercetin loaded polycaprolactone microspheres by simple adsorption technique to mimic extra cellular matrix and reduce immune or inflammatory responses at the site of implants. The collagen immobilization on polymeric scaffold surfaces through various surface modification techniques was the(More)
