Development and characterisation of medicated wound dressings for chronic wound healing
Chronic wounds are difficult to heal and exhibit physiological features including prolonged inflammatory phase, mixed bacterial flora resistance and formation of biofilms, ineffectiveness of topical antimicrobials and high volumes of wound exudate. Polymeric gels of Polyox (POL) and blends of POL …

A dressing solution for burn wounds: antibacterial and low-adherent wound dressings
… development of antibacterial and low-adherent wound dressings is urgently needed. Silver ion is a widely used antimicrobial agent, but its cytotoxicity remains a problem. In this study, low-adherent PAM (polyacrylamide) hydrogel incorporated with less toxic AgNP (silver nanoparticle), was …

Laser-processed parchment paper for fabrication of chronic wound dressings with selective oxygenation
<p>Chronic non-healing wounds (e.g., diabetic foot ulcers and bed sores) impact over 6.5 million Americans per year, costs in excess of $25 billion to treat on an annual basis, and are on the rise due to increasing levels of obesity and diabetes compounded by an aging population. A major inhibitor …

The development of novel smart wound dressings based on colloidal microgels and cotton fabric
… for free (unattached) microgels and novel wound dressings. Methyl paraben (MP) was used as a model drug compound. The results of MP release from free microgels show no significant influence of surface charge on MP release. However, BA-containing microgel particles release less MP than 100% …

The development of smart-bandage technologies
Healthcare associated infections of wound sites are a complex problem with substantial effects on patient morbidity and financial ramifications to healthcare bodies. The increasing interest in novel diagnostic strategies and preventing infections have led to an incursion of research into the topic. …

Evaluation of methods to account for release from nanofiber scaffolds
… use electrospun fibers for drug delivery and as wound dressings since the electrospun fibers have high surface area to volume ratio. In both situations, the release of either the additive or the drug needs to be controlled so that the fibers would release the additive or drug in a desired manner. …

Evaluation of Surface Acetylated Bacterial Cellulose for Antibacterial Wound Dressing Applications
Complications during the healing process of skin wounds often arise due to infection by pathogenic bacteria. Bacterial hydrolytic enzymes degrade the host tissue while biofilms can shield the bacterial cells from the host's immune response. Wound dressings with bacteriostatic or bactericidal …

A wound infection monitoring system
Infection control is a key aspect of wound management strategies. An infected wound results in chemical imbalances in the wound and may lead to prolonged healing times and wound surface degradation. Wound dressings changes may result in damage to healing tissues and an increased risk of infection. …
