Advanced Healthcare Materials, EarlyView.Gelatin methacryloyl (GelMA) granular hydrogel scaffolds (GHS) are fabricated using a generalized two‐step photocrosslinking approach to yield stable (non‐dissolving) microgels suitable for in situ covalent assembly under physiological conditions. A phase diagram is developed to define the interplay between individual microgel stability and scaffold ...

Task sequence planning in a robot workcell using AND/OR nets [PDF]
An approach to task sequence planning for a generalized robotic manufacturing or material handling workcell is described. Given the descriptions of the objects in this system and all feasible geometric relationships among these objects, an AND/OR net ...

Nanobody‐Decorated Lipid Nanoparticles for Enhanced mRNA Delivery to Tumors In Vivo
Advanced Healthcare Materials, EarlyView.This study presents a targeted mRNA‐LNP platform engineered with anti‐PSMA nanobodies for prostate cancer therapy. Using different in vivo models, the authors demonstrate selective uptake and mRNA delivery in PSMA+ cancer cells. However, while targeting is enhanced, mRNA delivery efficacy is limited by tissue penetration, tumor necrosis, and immune ...

Peptide Display Directed Assembly of Biopolymer Core–Silica Shell Particles
Advanced Healthcare Materials, EarlyView.Bacterial cells are engineered to produce biopolyester particles displaying peptides mediating growth of silica. Peptide‐coated biopolyester particles are treated with silica precursors and silica shell formation is studied. Transmission electron microscopy shows silica‐coated BPs which are formed after the silicification treatment. Characterization of
