Ultra-soft organic combined film with piezoelectricity induced by liquid-liquid interface polar engineering

open access: yesNature Communications
Although organic piezoelectric materials are increasingly being studied in the field of biomechanical sensing, the combination of high piezoelectricity and high softness is still a huge challenge due to the existence of steric hindrance effect.

Structure‐Property Relationships in Catecholamine Coatings for Broad Surface Functionalization

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by mussel adhesive proteins (MAPs), six catecholamine molecules with different molecular structure were systematically characterized and compared based on their ability to form homogeneous, reactive coatings. Highlighting candidates capable of balancing coating properties of interest, their successful use as primer layers for organic and ...

Hydrogels Augmented With Artificial Sweeteners can Inhibit Multidrug‐Resistant Acinetobacter baumannii Growth and Biofilm Formation While Demonstrating Safety in Pre‐Clinical Pilot Human Trials

open access: yesAdvanced Healthcare Materials, EarlyView.
Using PVA–borax hydrogels as carriers for off‐the‐shelf artificial sweeteners to fight multidrug‐resistant A. baumannii. These soft, biocompatible hydrogels rapidly reduce bacterial viability within multidrug‐resistant A. baumannii biofilms by more than 99% within one hour and sustain antimicrobial activity over time, while demonstrating safety in both

Engineering Concentration‐Dependent Intravitreal Mobility via Cyclic Arginine‐Enriched Nanocarrier Surface Modification: In Vivo Proof‐of‐Concept in a Porcine Large Animal Model

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...
