Self‑healing agarose–sucrose–borax hydrogel with ionic conductivity for 3D spheroid culture and microfluidic device fabrication

Materials & Design
This study reports the development of a versatile, ionically conductive, self‑healing (SH) hydrogel based on a combination of agarose, sucrose, and borax (AGSB). The hydrogel exhibits ionic conductivity and self-healing behaviour driven by dynamic borate-

Self-Healing Polymers From Principles to Applications

, 2013
Self-healing is a well-known phenomenon in nature: a broken bone merges after some time and if skin is damaged, the wound will stop bleeding and heals again.

Hydrogels Augmented With Artificial Sweeteners can Inhibit Multidrug‐Resistant Acinetobacter baumannii Growth and Biofilm Formation While Demonstrating Safety in Pre‐Clinical Pilot Human Trials

Advanced Healthcare Materials, EarlyView.
Using PVA–borax hydrogels as carriers for off‐the‐shelf artificial sweeteners to fight multidrug‐resistant A. baumannii. These soft, biocompatible hydrogels rapidly reduce bacterial viability within multidrug‐resistant A. baumannii biofilms by more than 99% within one hour and sustain antimicrobial activity over time, while demonstrating safety in both

Rare‐Earth–Functionalized Carbon Dot Hydrogels as Mechanically Robust Antibacterial Wound Dressings

Advanced Healthcare Materials, EarlyView.
The schematic depicts a dynamically cross‐linked PVA hydrogel network in which reversible borate ester bonds and hydrogen‐bonding interactions integrate lanthanum‐doped carbon dots (La‐CDs) and dipotassium glycyrrhizinate (DPG) to form a mechanically robust, multifunctional matrix.

Spatially Controlled Embedded Bioprinting of Prevascularized Spheroids‐Containing Biopatch Enables Functional Skin Regeneration

Advanced Healthcare Materials, EarlyView.
A spatially controlled embedded bioprinting strategy enables precise engineering of prevascularized multicellular spheroids within skin‐derived dECM bioinks. Optimized spheroid size, composition, and spacing promote vascular maturation, paracrine signaling, and tissue integration, resulting in enhanced angiogenesis, blood perfusion, and functional skin

Targeting CD300a Signaling With a Phosphatidylserine‐Presenting Hydrogel Rescues Macrophage Dysfunction and Accelerates Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the proposed mechanism: PEG/RGD‐PSLs mimic apoptotic cells to engage PS receptors (notably CD300a), transducing an inhibitory signal that suppresses the MyD88/NF‐κB pathway, leading to global anti‐inflammatory and pro‐reparative effects.

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.
