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

open access: yesAdvanced 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 ...

Metal–Organic Framework‐Based Antimicrobial Touch Surfaces to Prevent Cross‐Contamination

open access: yesAdvanced Materials, EarlyView.
A MOF‐based antimicrobial door handle cover is developed. It completely inhibits the cross‐contamination of Gram‐positive bacterial species (Staphylococcus aureus, and Enterococcus faecalis), Gram‐negative bacterial species (Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii), and fungi (Candida albicans). Abstract Infection diseases
