Engineered Sandwich‐Structured Composite Wound Dressings with Unidirectional Drainage and Anti‐Adhesion Supporting Accelerated Wound Healing (adv. Healthcare Mater. 8/2023)

Composite Wound Dressings In article 2202685 by Peng Yan, Xinguo Hou, and co-workers, a novel sandwich-structured composite wound dressing (SCWD), integrating a superlyophobic polydimethylsiloxane layer, a superlyophilic gauze layer, and a lyophobic PDMS layer, with particular unidirectional drainage capability and anti-adhesion properties, is presented. The application of SCWDs can reduce wound infection, avoid tissue avulsion when replacing dressings, and accelerate wound healing by approximately 20%. Aided by lyophilized powders of stem cells supernatant, the wound healing process is further improved.
