Wound Healing: An Overview of Wound Dressings on Health Care

Abstract

Chronic wound healing is a time-consuming and complicated process. Severe risk for wound healing that can be life-threatening is bacterial invasion and wound during the healing process. Therefore, it is necessary to use a sui barrier to create a controlled environment for wound healing. Various wound dressings such as hydrocolloids, hydrogels, sponges, foams, films, and micro and nanofibers have been explored in recent decades. High surface-to-volume ratio, high similarity to the biological structure of the extracellular matrix, high porosity and very small pore size are some advantages of nanofibers that have become potential candidates for wound healing applications. Different methods are used to fabricate nanofibers like drawing-processing, template synthesis, self-assembly, phase separation, force-spinning and electrospinning. Electrospinning is the most desirable method due to the possibility of producing independent, accessible and controllable nanofibers. The fiberbased wound dressings and their manufacturing methods have been extensively discussed.

“…Furthermore, it should enable proper gas exchange between the environment and the injured tissue, among other important functions. 7 Researchers are exploring various types of dressings to study the intricate process of skin wound healing. These include decellularized porcine dressings, hydrogels, freeze-dried dressings, gas-foaming dressings, and dermal matrix-based structures.…”

Investigating the electrochemical and antibacterial activities of nickel pyrophosphate [a-Ni2P2O7] nanostructures

“…Among different types of nanomaterials, transition metal-based nanomaterials attain huge interest in various applications because of their low cost, bio-compatibility, excellent redox properties, and environmental friendliness. More specifically, transition-metal phosphate-based nanomaterials (CuMnPO 4 , CoMnPO 4 , LiFePO 4 , Ni 3 (PO 4 ) 2 /Co 3 (PO 4 ) 2 , Cu 2 P 2 O 7 ) have been fascinating wide attention in supercapacitors, metal-air batteries, water splitting, photo-catalytic degradation, and bio-medical applications due to their high electronic conductivity, catalytic properties and natural richness [1][2][3][4][5]. Especially, pyrophosphate-materials such as Co 2 P 2 O 7 , Mn 2 P 2 O 7 , and, Ni 2 P 2 O 7 have attracted much attention in recent years among various research groups due to their large interconnecting open channel network, facile electrolyte ion transportation which can improve electronic conductivity [6][7][8].…”
