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. …

Antibiotic-free antibacterial hydrogels for wound healing applications
… cellulose (BC) has attracted great interest as a wound dressing thanks to its innate hydrogel-like structure and high biocompatibility. However, the lack of antibacterial features of cellulose poses some limitations to its use, especially in the context of increasing antimicrobial resistance. In …

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 …
