Catheter-related infection and thrombosis are serious complications, and preventative coatings are not always suitable. Here, the authors report a heparin mediated coating for to address both infections and thrombosis from catheters simultaneously.

The collective intermolecular dynamics of protein and water molecules, which overlap in subterahertz frequencies, are relevant for protein function expressions. Here the authors develop highly sensitive dielectric measurements, revealing that protein hydration is nonthermally accelerated by sub-terahertz irradiation.

We investigated the effect of the hydrophobicity of the side chains of mixed-charge polymers on their interaction with cancer cell membranes. Six pH-responsive mixed-charge polymeric micelles consisting of cationic, anionic, and neutral moieties were created, with differences in hydrophobicity generated by altering the type of anionic monomer and the ratio of the hydrophobic spacer moiety. Evaluation of their affinity for cell membranes revealed that increases in the hydrophobicity and pH-responsive nature led to pH-selective toxicity, which was assumed to be caused by the disruption of cell membrane integrity.

Transplantation of helpful bacteria has been used to treat disease through modulating host microbiota. Here, the authors report a strategy to control bacteria localization in the jejunum, via an in vivo in-situ thiol-disulfide exchange reaction between surface-reactive bacteria and mucous.

Hybrid bilayer membranes (HBMs) are an advanced organic–inorganic platform for energy catalysis and biomimicry. This Review highlights the design principles, key developments, major achievements and prospects of HBM technologies.

Nanoparticle elasticity is known to affect physiological fate but how this occurs is largely unknown. Here, the authors report on a study using nanoparticles differing in elasticity alone to show a difference in the protein corona, in particular apolipoprotein A-1 absorption, corresponds to differences in circulation time.

A model based on the well-known β-cyclodextrin–adamantane receptor–ligand pair has been used to obtain important insight into the kinetics of gradient-driven motion across a surface.
