Scientists are expected to develop stem cell nano "Band-Aids"

Recently, Qin Yan, a researcher at the Institute of Biophysics, Chinese Academy of Sciences, and Wen Yongqiang, a professor at the University of Science and Technology Beijing, have made new progress in stem cell-nano wound materials

Janus nanofiber aerogel has enhanced mechanical properties and liquid absorption capacity, and also retains the inherent soft texture and extracellular matrix-like structure of nanofibers

"Different from the weak function of traditional band aids in promoting wound healing, the nanofiber aerogel we developed is a fiber that is thinner than a thousandth of a hair, and is highly similar to the extracellular matrix structure

According to reports, this nanofiber aerogel named Janus can be used as a functional nanofiber dressing to regulate wound exudate

The skin can resist the external environment's invasion of the body

To overcome this dilemma, surgical debridement must be used, which may cause secondary trauma and severe pain

To this end, through the physical and chemical modification of nanofibers, the research team obtained a variety of structures and functions of nanofiber wound dressings

"Although the mechanism of diabetic wounds is still elusive, multifunctional wound dressings that can interfere with exudate open up a new path for the practical application of diabetic wound healing
