Biomimetic synthetic functional materials are valuable for a large number of practical applications with improved or tunable performance. In this paper, we present a series of mussel-inspired biomimetic catechol-containing copolymers synthesized from dopamine methacrylamide (DMA) and 2-(2-ethoxyethoxy)ethyl acrylate (EEA) and abbreviated as poly(PDMA-PEEA). The successfully synthesized adhesive polymers allow adhering polytetrafluoroethylene (PTFE) and were used for coating PTFE particles in organic solvent and re-dispersion in an aqueous medium. Adhesive polymer coated PTFE particles were efficiently used as a nanoreactor for generating silver (Ag) metal nanoparticles (NPs).

A collagen-inspired helical protein-mimic has been synthesized via topochemical polymerization of a designed tripeptide monomer. In the monomer crystal, molecules arrange in a head-to-tail manner, forming supramolecular helices. The azide and alkyne of adjacent molecules in the supramolecular helix are proximally preorganized in a ready-to-react arrangement.

This study provides a comprehensive investigation of antimicrobial additives (ZnO/AgNPs and SiO/AgNPs) on the properties of biodegradable ternary blends composed of poly(hydroxybutyrate) (PHB), poly(lactic acid) (PLA), and polycaprolactone (PCL) by examining the morphology, thermal stability, crystallinity index, and cell viability of these blends. Overall, transmission electron microscopy (TEM) analysis revealed that AgNPs and SiO exhibited comparable sizes, whereas ZnO was significantly larger, which influences their release profiles and interactions with the blends. The addition of antimicrobials influences the rheology of the blends, acting as compatibilizers by reducing the intermolecular forces between biopolymers.

Objectives: Drug-loaded mucoadhesive silk fibroin (SF) microneedle patch can overcome the limitations of low bioavailability and significant pain associated with traditional treatment methods, such as topical application or injection of triamcinolone for oral submucous fibrosis (OSF). However, these systems release the drug too quickly, failing to meet the clinical requirements. This study aims to construct a mucoadhesive SF microneedle patch pre-assembled with silk fibroin nanospheres (SFN) and explore its ability to sustain the release of triamcinolone in the treatment of OSF.

Delayed wound healing remains a major challenge in biomedical research, often leading to complications such as scarring, acute trauma, and chronic diseases. Effective wound management is crucial for enhancing treatment outcomes, preventing complications, and promoting tissue regeneration. In response to this need, a variety of polymeric biomaterials have been developed.

To effectively utilize sesbania gum in coal dust control and address the limitations of excessive viscosity and mediocre strength, oxidation treatment was used to improve its fluidity. Polyvinyl alcohol (PVA) and sodium trimetaphosphite (STMP) were used to enhance oxidized sesbania gum OSG, and crosslinking technology was used to improve its mechanical stability. This study developed a novel foam dust suppressant OSG-PVA/SDBS by response surface design, and the optimized dust suppressant material exhibited excellent adhesion and curing properties.
