Organelle Localization‐Induced Bio‐Orthogonal Polymerization (OLIBOP) for Photostable Super‐Resolution Live‐Cell Imaging

open access: yesAdvanced Healthcare Materials, EarlyView.
Organelle localization‐induced biorthogonal polymerization enables direct synthesis of photostable poly‐AIEgens within targeted organelles for super‐resolution live‐cell imaging. ABSTRACT Real‐time monitoring of dynamic biological processes demands fluorescent probes that can withstand prolonged light exposure without photobleaching—a critical ...

A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Shellac‐Mediated Assembly of Nanoparticles for mRNA Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
A shellac‐mediated nanoparticle assembly strategy is presented, involving the complexation of mRNA and low‐molecular‐weight cationic molecules (e.g., polyethyleneimine, chitosan, lipids, and poly‐l‐lysine), followed by capping with shellac. This nanoparticle platform enables mRNA transfection following intravenous injection and facilitates gene editing

Oxygen Supply of Islets of Langerhans by Photosynthetically Active Microalgae in Bioprinted Co‐Cultures Maintains Their Function in a Hypoxic Environment

open access: yesAdvanced Healthcare Materials, EarlyView.
This study developed a bioprinted co‐culture system embedding rat pancreatic islets and Scenedesmus sp. microalgae spatially defined in close vicinity. Red light was found optimal to ensure microalgal photosynthesis while maintaining islet viability and functionality. A tailored co‐culture medium supported both cell types.
