Structure-guided protein engineering increases enzymatic activities of the SGNH family esterases

Biotechnology for Biofuels, 2020
Background Esterases and lipases hydrolyze short-chain esters and long-chain triglycerides, respectively, and therefore play essential roles in the synthesis and decomposition of ester bonds in the pharmaceutical and food industries.

Oxygen‐Inhibition Driven Compartmentalization of Dextran Microgels: Toward Fusible Colloidal Biomaterial Inks for 3D Printing

Advanced Materials, EarlyView.
Harnessing oxygen inhibition as a materials design principle enables the universal fabrication of core–shell microgels with tunable radial crosslinking gradients. This conceptually simple yet highly versatile strategy generates fusible colloidal bioinks that combine structural hierarchy with adaptive porosity.

Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

Advanced Materials Interfaces, EarlyView.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...

Mitochondria‐Specific Protein Delivery by Protease‐Triggered Release in Plants with Single‐Walled Carbon Nanotubes

Advanced Materials Technologies, EarlyView.
Polymer‐coated carbon nanotubes were engineered as protease‐responsive nanocarriers for protein delivery in intact plants. GFP cargo can be released by cytosolic phytaspase cleavage and subsequently targeted to mitochondria via an N‐terminal sequence, enabling controlled intracellular protein delivery without tissue damage and demonstrating stable ...

Astrocyte Enrichment of 3D Cortical Constructs Enhances Brain Repair

Advanced Science, EarlyView.
This study highlights the role of astrocytes in supporting neural progenitor cell survival and differentiation after traumatic brain injury. Astrocytes enhanced neuronal differentiation, improved cell survival in co‐cultures, and promoted integration of microfluidics‐based implants with host tissue following implantation. Additionally, increased axonal
