Medical Fabrics with Non‐Antibiotic, Supramolecular Antimicrobial Coatings: A Preventive Approach to Combat Biofilm Formation and Bacterial Dissemination

Advanced Healthcare Materials, EarlyView.
The study presents an antibiotic‐free strategy using medical fabrics coated with supramolecular assemblies of polyarginine and hyaluronic acid. These coatings showed strong antimicrobial and anti‐biofilm activity in vitro and in vivo, achieving major bacterial load reductions, including against MRSA.

3D‐Printed Titanium Implants with Bioactive Peptide‐Polysaccharide Scaffolds for Personalized Bone Reconstruction

Advanced Healthcare Materials, EarlyView.
Porous 3D‐printed titanium implants are made bioactive by integration with a supramolecular peptide‐hyaluronic acid nanofibrillar scaffold, without the addition of exogenous cells or growth factors. Uniform filling of the implant architecture promotes vascularized, spatially homogeneous bone regeneration, significantly enhancing osteogenesis throughout

Rainbow Photonic Crystals: Self‐Assembly of Carbohydrate Bottlebrushes Block Copolymers

Advanced Materials, EarlyView.
Full‐color reflective 1D photonic crystals, capable of a tunable, responsive, and reversible color with high repeatability, are created from the self‐assembly of carbohydrate‐based brush block copolymers (BR01‐04). Abstract Tunable and responsive photonic crystal systems are the subject of great research interest owing to their ability to actively ...
