The Lab key focus is on understanding and designing biomaterials using biomimetic approach for tissue regeneration. Our research interests are development of injectable hydrogels, electrospun scaffolds and scaffolds for wound healing.
The desire and need to minimize traditional open surgeries is gearing up as it could reduce the healthcare expenses and improve the recovery time for the patients. Injectable hydrogels with their ease of handling, complete filling of the defect area and good permeability have emerged as promising biomaterials. The Jayakumar group designs shear thinning injectable hydrogel and in situ cross-linked hydrogel with bio-inspired polymers and nanoparticles for tissue regeneration. Injectable hydrogels are designed for effective regeneration of functional tissue, such as bone, fat, and cartilage. Further, work is also been directed towards achieving therapeutic angiogenesis in order to revascularize ischemic tissues and in developing cost effective injectable hydrogel and bioadhesive hydrogel for haemostatic applications. Bioadhesive hydrogel loaded with antibacterial drug is being developed for treating mediastinitis.
Electrospun fibres’ possess unique properties promise to make key bioengineered material for tissue regeneration. We fabricate fibres in different 3-D forms so as to make layered tubular constructs, thick layered fibrous scaffolds, braided and rolled fibre scaffolds. The Jayakumar group is developing approaches to control cell differentiation through surface modification of electrospun fibres. Further, work is also directed towards designing scaffolds for tendon and ligament regeneration using electrospun fibre scaffold.
Natural process of wound healing is impaired in many pathological conditions, resulting in chronic wounds. Pathological conditions arising as of diabetic conditions, hyperfibrinolytic conditions, polymicrobial infection, burn wounds etc are create different complications in the treatment for wound healing. The underlying pathology in these conditions is not fully understood. The Jayakumar group in developing bandages in addressing in the problems in the above mentioned situations
