Rational Design of Unsaturated, Thioether Ionizable Lipids for Enhanced In Vivo mRNA Delivery

Advanced Healthcare Materials, EarlyView.
Lipid nanoparticles (LNPs) have rapidly become the delivery system of choice for RNA therapeutics. Here, a rational design approach is taken to improve the effectiveness of LNPs based on an ionizable thioether lipid library. The incorporation of unsaturated tails and bulkier, hydrophobic head groups significantly enhances their functionality and ...

Immunosuppressive Cytokine‐Tethered Hydrogel for Treating Rheumatoid Arthritis

Advanced Healthcare Materials, EarlyView.
An injectable hydrogel is developed by chemically tethering IL‐4, an immunosuppressive cytokine, to a hyaluronic acid‐based backbone. The hydrogel reduces joint friction and exerts immunomodulatory effects. In a rheumatoid arthritis (RA) mouse model, it reduced inflammation, preserved cartilage, and promoted anti‐inflammatory immune responses.

Detection of Genetically Modified Foods

, 1999
In recent years, Genetically Modified (GM) foods have become increasingly common on our supermarket shelves. Consumer concerns regarding their safety have prompted codes of practice and legislation requiring labelling of all GM-food-containing products. Labelling requires some means of verification.

A Bio‐Inspired Perspective on Materials Sustainability

Advanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...

Engineering Magnetotactic Bacteria as Medical Microrobots

Advanced Materials, EarlyView.
Magnetotactic bacteria (MTB) are living microorganisms that produce magnetosomes for navigation using the Earth's geomagnetic field. Their built‐in magnetic components, along with their intrinsic and/or modified biological functions, make them one of the most promising platforms for making future living and programmable microrobots.

Hydrogel‐Mediated Preservation of Live Tumor Explants for Drug Development in Peritoneal Metastases

Advanced Materials, EarlyView.
This study presents a hyaluronan‐based hydrogel platform preserving the native tumor microenvironment (morphology, tissue composition, histology) of patient‐derived explants from peritoneal metastases, enabling clinically relevant drug screening. Hydrogel properties such as stiffness and degradation are crucial for longer‐term histoculture.
