Developing functional medical materials is urgent to treat diabetic wounds with a high risk of bacterial infections, high glucose levels and oxidative stress. Here, a smart copper‐based nanocomposite acidic spray has been specifically designed to address this challenge. This copper‐based nanocomposite is pH‐responsive and has multienzyme‐like properties. It enables the spray to effectively eliminate...
Intervertebral disc degeneration (IVDD) is a significant contributor to low back pain, characterized by excessive reactive oxygen species generation and inflammation‐induced pyroptosis. Unfortunately, there are currently no specific molecules or materials available to effectively delay IVDD. This study develops a multifunctional full name of PG@Cu nanoparticle network (PG@Cu). A designed pentapeptide,...
Intervertebral Disc Degeneration
In article number 2308167, Pooyan Makvandi, Yunlong Zhou, Aimin Wu, and co‐workers prepared a multifunctional metal polyphenol nanoparticle that exhibited the ability to escape lysosomal capture and effectively targeted mitochondria to scavenge excess reactive oxygen species. The results of in vitro and in vivo experiments showed that the nanoparticles retarded disc...
Traditional alternating current filter based on aluminum electrolytic capacitors (AECs) suffer from abrupt drop of filtering capability at ultra‐low temperatures (≤−30 °C), which greatly hinders the reliable working of electronics at extremely cold conditions. Herein, an ultra‐low‐temperature alternating current (AC) filter for the first time enabled by high‐frequency supercapacitor based on covalently...
