Wound healing is a complex and dynamic process, and metabolic disturbances in the microenvironment of chronic wounds and the severe symptoms they cause remain major challenges to be addressed. The inherent properties of hydrogels make them promising wound dressings. In addition, biomembrane-based nanostructures and microstructures (such as liposomes, exosomes, membrane-coated nanostructures, bacteria and algae) have significant advantages in the promotion of wound healing, including special biological activities, flexible drug loading and targeting. Therefore, biomembrane-based nanostructure- and microstructure-loaded hydrogels can compensate for their respective disadvantages and combine the advantages of both to significantly promote chronic wound healing. In this review, we outline the loading strategies, mechanisms of action and applications of different types of biomembrane-based nanostructure- and microstructure-loaded hydrogels in chronic wound healing.

Wound bacterial infections not only impede the healing process but can also give rise to a range of serious complications, thereby posing a substantial risk to human health. Developing effective wound dressings incorporating phototherapy functionalities, specifically photothermal therapy (PTT) and photodynamic therapy (PDT), remains a critical area of research in modern wound care. Existing PTT-PDT systems often suffer from challenges such as nanoparticle aggregation and inefficient reactive oxygen species (ROS) generation, which are essential for therapeutic efficacy.

Bacterial infections and excessive accumulation of wound exudates remain the main obstacles and clinical challenges to the healing of chronic cutaneous wounds. Conventional dressings are commonly used medical materials for acute wound care, but they do not possess the bacterial infection resistance required for chronic wound treatment. Herein, we prepared pure chitosan nanofibrous membranes (C) by electrospinning with poly(ethylene oxide) (PEO) as a sacrificial additive and then loaded with zinc-based metal-organic framework (MOF) as a novel antimicrobial wound dressing.

Acne leads to significant social withdrawal, depression, and disfiguring scars in many cases. Available treatments are characterized by high rates of relapse, dangerous side effects, and social stigma, which often leads to poor patient compliance and treatment failure.
