Summary: This study examined the potential application of antibacterial and cyto-compatible tricomponent composite electrospun nanofibers comprised of polyvinyl alcohol (PVA), copper II oxide nanoparticles (CuONPs), and Momordica charantia (bitter gourd, MC) extract as an effective wound dressing. The addition of MC extract reduced the toxic effects of CuONPs and provided antioxidant properties. The optimized samples demonstrated good antibacterial properties with reduced toxicity, excellent cell adhesion and cytocompatibility, and slightly improved mechanical properties.

Summary: In this study, CuO nanoparticles were synthesized via hydrothermal synthesis and then modified with different polymers to optimize bacteriostatic effects. Among them, PDA-modified CuO NPs showed excellent antibacterial activity with a bacteriostatic rate of 85.8%. Their superior performance can be attributed to their smaller size, surface charge, and favorable van der Waals interactions at pH 7.4, which increased their affinity for the lipopolysaccharide-containing outer membrane of E. coli.

Summary: Antibiotics have led to the emergence of drug-resistant bacteria due to their misuse and abuse. Antibacterial peptides (AMPs) have shown promise as alternative drugs to antibiotics, as they possess broad-spectrum antibacterial activity and are less likely to cause resistance. However, their clinical application is limited by high cytotoxicity and low antibacterial efficiency. This study developed an antibacterial peptide with DNA cleavage function, which demonstrated excellent antibacterial activity, wound healing promotion, and anti-skin infection capability.

Summary: The study compared the electrospinning of various polylactide and polycaprolactone copolymers and homopolymers. The results showed that the electrospinnability of polymeric solutions depends on molecular weight and the PLA/PCL ratio in the final copolymer. Degradation rates were influenced by molecular weight, polymer crystallinity, and enzyme specificity, with differences in degradation impact between lipase and Proteinase K observed. Electrospun PLLA materials were found to support fibroblast adhesion and proliferation, and all tested materials were cytocompatible with 3T3 mouse fibroblasts.

Summary: This study developed biocompatible nanofibrous mats with antiadhesive surfaces inspired by the lotus leaf nanostructure. A combination of needleless electrospraying and electrospinning technology was used to mimic the structure, and the surface hydrophobicity was enhanced by cold plasma modification using a chemical vapor deposition method. The material's morphology, wettability, and chemical composition were observed over a period of six months, and cytocompatibility and antiadhesive behavior were confirmed through in vitro tests.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

Summary: This study focuses on the development of high-performance, low-migration photoinitiators. A polymerizable photoinitiator (VBP) was synthesized by introducing an ethylene group into benzophenone, and three different molecular weight single-component photoinitiators (PVBN1-3) were synthesized based on VBP. The results show that these new photoinitiators have stronger absorption ability compared to benzophenone and significantly reduce the migration of initiators and co-initiators, addressing the safety concerns caused by migration.

Summary: This study investigates the effect of plasma treatment on carbon nanotubes (CNTs) and the structure/properties of polyimide (PI) nanocomposites with ultra-low content of CNTs. The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.

Summary: The insertion of rigid aliphatic or aromatic building blocks in polymer structures is an effective way to synthesize high -Tg polymer materials. In this study, a series of isosorbide-2-aryl carboxylate-5-methacrylate monomers (ArIMAs) were synthesized by functionalizing isosorbide 5-methacrylate with various aromatic lignin-inspired esters. These monomers were polymerized to obtain high molecular-weight poly(aryl carboxylate isosorbide methacrylates) (PArIMAs). The resulting polymers showed high glass transition temperatures and thermal stability, making them suitable for use as high-performance plastics and coatings.
