March 25, 11:30 AM – 1:00 PM EST, Virtual
Join the Chemical Applications Interest Group members to explore the latest developments in antimicrobial textile research. Attendees will then have the opportunity to interact in a Q&A session to learn more about their research!
Living Materials with Embedded Probiotics for Treating Wound Infections
Presented by Dr. Qun Ren, Lead Researcher on Bacteria and Materials Interactions, Empa
Empa fabricated ProGel which is an innovative living hydrogel that addresses the challenge of wound infections and antibiotic resistance. It contained probiotic in a gelatin-based matrix, and can be applied easily with a double-syringe system. ProGel displayed broad-spectrum antimicrobial efficacy against common wound pathogens, maintains high probiotic viability, and showed cytocompatibility with human dermal fibroblasts. Its effectiveness in preventing biofilm formation has been demonstrated in human skin wound models, making it a promising solution for managing complex wound infections.
Mother Nature’s Own Technology
Presented by Pedro Santos, Microbiology Laboratory Manager, HeiQ Portugal
Probiotics are nature’s technology for textile enhancement, offering a sustainable and safer alternative to synthetic chemicals. By using living organisms, textiles can naturally reduce allergens, improve skin appearance, and minimize odors in garments. Probiotics are biodegradable, eco-friendly, and cost-effective, ensuring long-term benefits without environmental harm. As part of HeiQ’s bio-tech innovations, they deliver targeted, intelligent functionality while aligning with sustainability goals.
