Spatial Patterning of Modular Gelatin‐Peroxide Microspheres in Melt‐Electrowritten Scaffolds Provides Controlled Oxygen Generation and Mitigates Hypoxia and Cytotoxicity

Advanced Healthcare Materials, EarlyView.
A bioassembly approach is described using photo‐crosslinked gelatin‐based microgels containing calcium peroxide (CaO2) to generate oxygen (O2) and enhance cell survival in hypoxic conditions (1% O2). Bioassembly enables spatial patterning of individual CaO2‐laden and mesenchymal stem cell (MSC)‐laden microgels and allows for decoupling and mitigating ...

Strategies to Improve the Lipophilicity of Hydrophilic Macromolecular Drugs

Advanced Healthcare Materials, EarlyView.
Hydrophilic macromolecular drugs can be successfully lipidized by covalent attachment of lipids, by hydrophobic ion pairing with negatively or positively charged surfactants, and by dry or wet reverse micelle formation. Lipophilicity enhancement of hydrophilic macromolecules has several benefits including stability and bioavailability improvement ...

Photosensitizing Lipid Nanoparticles for Ferroptosis‐Enhanced Photodynamic Cancer Therapy via GPX4 Silencing

Advanced Healthcare Materials, EarlyView.
Photosensitizing lipid nanoparticles (PLNPs) are engineered by incorporating cholesterol–PEG–pheophorbide a into MC3‐based LNPs and encapsulating GPX4‐targeting siRNA. Upon light activation, PLNPs generate reactive oxygen species (ROS) while silencing GPX4 to induce ferroptosis.
