Ultra‐Fine 3D Bioprinting of Dynamic Hyaluronic Acid Hydrogel for in Vitro Modeling
3D bioprinting merges tissue engineering and additive manufacturing to create biological structures. A bioink is developed by modifying hyaluronic acid, a natural extracellular matrix polymer, with cysteine. Potassium iodide is later added to tune gelation kinetics, enabling fine printing with a 32G needle.

Traceless Photopolymerization with Non‐Pulsed Red Light Enables 3D‐Printable Cell‐Laden Hydrogels
The paper presents a red‐light‐induced polymerization process, initiated by the FDA‐approved dye methylene blue and the cytocompatible co‐initiator triethanolamine, for fabricating hydrogels. This photopolymerization process is oxygen‐tolerant, cytocompatible, and, most importantly, leaves no color traces, resulting in completely transparent scaffolds.

Surprisingly, a cell can bind to itself to make a self‐adhesion, which engineered here to improve how cells attach to biomaterials. Nanoprinting are used to make 3D structures smaller than cells–called Self‐Adhesion‐Tunnels (SATs)–around which cells can wrap and bind to themselves.

Bioinspired Smart Nanogels for Rapid Blue Laser‐Activated Hemostasis in Gastrointestinal Bleeding
Waxberry‐inspired branched‐silica nanogel can swiftly stop bleeding upon blue laser endoscopy for gastrointestinal hemostasis in the esophagus, stomach, and duodenum of mini‐pigs. Abstract Gastrointestinal bleeding (GIB) is a critical condition that requires rapid and effective intervention.

P3HT‐Based Electroactive Films for In Vitro Neuronal Cell Interfacing
Reducing the mechanical mismatch between bioelectronic devices and tissue is crucial for enhancing the characteristics of biointerfaces that better mimic the biological tissues. This work investigates the physico‐chemical properties of tunable nanostructured surfaces obtained from a blend of P3HT and MWCNT electroactive polymer.

3D Printed Magnetic Origami Scaffolds for Guided Tissue Assembly
3D‐printed magnetic origami scaffolds enhance 3D coculture by directing cell proliferation pre‐folding, restricting expansion for controlled growth within the channel, and spatially and temporally promoting 3D multicellular dissemination post‐folding.
