Manipulation of Oxygen Tension in Damaged Regions via Hypoxia‐Induced IPN Hydrogel Microspheres for Intervertebral Disc Regeneration

open access: yesAdvanced Science, EarlyView.
A novel interpenetrating network hydrogel microsphere (NSC‐Exos@HIMS) is developed to manipulate oxygen tension in damaged regions and recruit endogenous stem cells. In vitro and in vivo results show that NSC‐Exos@HIMS maintains the hypoxia microenvironment for up to 5 days, which triggers nucleus pulposus cell‐like differentiation and enhanced ECM ...

New Insights into Heavy Metal Sequestration Through Metal‐Phenolic Network‐Confined Nano‐HFO: Overlooking Iron Utilization and Modulating Electron Density

open access: yesAdvanced Science, EarlyView.
Iron‐based nanocomposites are widely used for trace heavy metal removal, but the low utilization of HFO nanoparticles remains a challenge. Here, a metal‐phenolic network (MPN) strategy is proposed to confine nano‐HFO within polystyrene beads, creating a negative electrostatic field and optimizing electron density at oxygen sites. This approach enhances
