A review on wound dressings: Antimicrobial agents, biomaterials, fabrication techniques, and stimuli-responsive drug release

Skin, the largest organ of the body, protects the inner organs against the ambient environment, and it is prone to internal and external injuries in the form of wounds. The wound healing process of the body can be hindered by a compromised immune system or severity of the wound, making wound care critical under these circumstances. Infection is the most prevalent complication that arises in wounds, and wound dressings are widely used to assist the self-healing process of the body for complete skin recovery. In this review, the recently developed wound dressings are reviewed, focusing on reviewing various antimicrobial agents, biomaterials, and fabrication techniques. In moving toward green chemistry, the importance of using non-toxic solvents for fabricating wound dressing is emphasized. Finally, the importance of using stimuli-responsive wound dressings as a recent trend in wound dressing is highlighted. The outcome of this review will lead to novel research in the field of wound dressing and drug-eluting constructs.
