Summary: Different magnetic nanomaterials were studied, with a focus on the transport of drugs under a magnetic field. The unique characteristics of each magnetic nanostructure, such as size, shape, surface modification, and composition, make them suitable as nanocarriers. In this study, novel manganese-cobalt co-incorporated magnetic ferrite nanoparticles were synthesized hydrothermally and characterized. These nanoparticles were coated with β-cyclodextrin, folate, and polyethylene glycol, allowing for effective drug loading with a high encapsulation efficiency of approximately 93%. The drug-loaded nanocarriers exhibited a slow and sustained release of the drug over 130 hours, showing increased efficacy compared to the free drug. The results highlight the significance of these designed nanocarriers as potential anticancer drug vehicles.

Summary: Cancer therapy is a global challenge, but a variety of promising anticancer therapeutics have been developed. However, their direct administration often fails to achieve the desired efficacy due to low bioavailability and poor tissue selectivity. Polymers offer advantages for drug delivery, yet are generally poorly targeted to the tumor microenvironment (TME). The relatively lower acidity of the TME provides a specific trigger for the development of polymers for targeted delivery, and this article summarizes the strategies, mechanisms, and applications of acidity-sensitive polymers for delivering various anticancer therapeutics.

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.
