A hydrogel wound dressing ideally designed for chronic wound care

Chronic wounds are a major challenge to public health around the world and place an enormous financial burden on the government of every nation. Wound dressings that can facilitate wound healing have long been investigated. Based on the pathological characteristics of chronic wounds, in a recent issue of Matter, Zhao and colleagues reported a novel hydrogel scaffold using 3D bioprinting technology. The integration of multiple functions is well adapted to the care needs of chronic wounds and has been verified in animals with infected chronic wounds. The application of these new technologies is an important contribution to the development of new clinical dressings.

In situ 3D-bioprinting MoS2 accelerated gelling hydrogel scaffold for promoting chronic diabetic wound healingDing et al.MatterJanuary 23, 2023In BriefAn MoS2 accelerated gelling hydrogel scaffold for accelerated infected chronic wound healing via microfluidic-assisted in situ printing was designed. When directly printing the scaffold in chronic diabetic wounds, the scaffold exhibited a protective capacity to fibroblasts against oxidative stress by decomposing excessive ROS into O2 and killed bacteria under NIR irradiation, thus facilitating the infected chronic wound healing.
