Abstract Wound healing is a complex and dynamic process essential for restoring the integrity of damaged skin. It requires wound dressings that actively regulate the wound microenvironment by preventing infection, maintaining moisture balance, allowing gas exchange, and managing exudate. Natural polysaccharides, such as konjac glucomannan (KGM), chitosan, and cellulose, are well suited to this role because of their biocompatibility, biodegradability, and intrinsic bioactivity. Extensive research has focused on developing polysaccharide-based wound dressings with enhanced functionality to promote healing. This review examines recent scientific research published mostly in the past five years on the development and application… More > Graphic Abstract

Abstract The objective of this study is to develop chitosan-based films containing Hypericum perforatum L. and/or Citrus limon L. oils and to investigate their suitability as novel wound dressing materials. The morphology of the chitosan-based films were observed by means of employing the scanning electron microscopy (SEM) and the chemical structure characterization was performed via Fourier Transform Infrared Spectroscopy (FTIR). Hypericum perforatum L. and/or Citrus limon L. were successfully incorporated to the chitosan films. Antibacterial, swelling, and mechanical properties of these films were investigated. The antibacterial property was enhanced by incorporating Hypericum perforatum L. and Citrus More >

Abstract The fourth most predominant overwhelming type of trauma is burn injuries worldwide. Ideal wound healing dressings help in the wound healing process in a lower time with less pain. Commonly used dry wound dressing, like absorbent gauze or absorbent cotton, possess limited therapeutic effects and require repeated use, which further exaggerates patients’ suffering. In contrast, hydrogels films present a promising alternative to improve healing by guaranteeing a moisture balance at the wound site. The aim of the current study was to synthesize Tamarix aphylla (T. aphylla) extract-loaded hydrogel film with Na-CMC and pectin and to study their… More >

Abstract A silk fibroin (SF) spongy wound dressing incorporated with silver nanoparticles (Ag-NPs) was developed for biomedical applications. Ag-NPs were efficiently synthesized in situ via ultra violet (UV) with AgNO₃ as precursor and silk fibroin as reducing and protecting agent, respectively. After lyophilization, the formed silk fibroin spongy wound dressing (SFWD) exhibited polyporous morphology and inner lamellae structures, with uniform dispersion of Ag-NPs. The porous structure provided SFWD with the ability to absorb tissue exudatealmost 6 times of its own weight, which could guarantee the sustained release of Ag-NPs. By methanol treatment, SFWD showed much improved mechanical properties… More >

Abstract A series of hydrogels with different ratios of chitosan and licorice polysaccharide (LP) were prepared by crosslinking to different concentrations of genipin (gp). They were characterized by FTIR (Fourier transform infrared spectroscopy), SEM (Scanning electron microscope), swelling ratio, rheological measurements, degradation with time, cytotoxicity, and antibacterial efficacy. Results show that the hydrogels have porous structures. With an increase in LP content, the swelling rate grows in the early stage of immersion in buffer and drops later. The swelling ratio ranged from 986% to 1677%, and stiffness varied from 777 Pa to 1792 Pa. The addition… More >

Abstract Silver nanoparticles (AgNPs) were synthesized by a bio-reduction method using an aqueous extract of mullein leaves (Verbascum thapsus L.) functioning as reducing as well as a stabilizing agent. Various synthesis parameters such as reaction time, temperature and concentration of the extract were also studied for the synthesis of AgNPs. The so prepared AgNPs were characterized by various techniques including UV-Vis spectroscopy, X-ray diffraction, scanning electron microscopy (equipped with energy dispersive analysis of X-rays), and transmission electron microscopy. The electron microscopy images suggest the formation of polydispersed spherical AgNPs with average particle size of about 20 More >
