Pathogenic microbial contamination poses serious threats to human healthcare and economies worldwide, which instigates the booming development of challenging antibacterial materials. N-halamine fibrous materials
. Cellulose is a suitable candidate to be functionalized withN-halamines due to abundance of hydroxyl groups on its backbone which can be easily grafted withN-halamine [147]. VariousN-halamine precursors with reactive agents including epoxy groups and organosiloxane have been grafted onto cellulose...
necessitating urgent and innovative interventions. In response to this peril, scientists have embarked on the development of advanced biocompatible antibacterial materials, aiming to counteract not only bacterial infections but also the pervasive issue...
α-Chymotrypsin could also be loaded into the 1L6 scaffolds, giving rise to materials with enzymes that could accelerate degradation and tissue regeneration. Adhesion and proliferation of epithelial (Vero) and fibroblast (Cos-7) cells on 1L6 films and scaffolds demonstrated the biocompatibility of the...
Preparation, characterization and antibacterial properties of hydro-charged melt-blown nonwovens coated with an N-halaminedoi:10.1039/D4NJ01962HAir filtration materials can protect humans from the invasion of airborne pathogens. However, pathogens intercepted by air filters can survive in fibrous ...
Among these biocides, N-halamine structures have features of high efficiency, durability and rechargeability to kill bacteria, making them ideal functions for air and water filtering materials. Some antibacterial nanofibrous membranes with N-halamine precursors have been developed by using electrospinning...
Findings reported in another recent publication revealed that the introduction of chitosan N-halamine conjugates in hemostatic wound dressings resulted in a one million-fold reduction in the extent of microbial contamination [17]. Other applications for chitosan that have been widely described in the ...

Several hybrid membranes were prepared by chemical bonding of N-halamine/ZnO nanoparticles onto poly-蔚-caprolactone (PCL) using a free radical polymerization strategy. The chlorination process led to the formation of N-Cl bonds. Hybrid membranes were characterized by scanning electron microscope, ...
In this study, we generated fibrous membranes with biodegradable polyester polyhydroxybutyrate and poly-蔚-caprolactone (PHB/PCL) by electrospinning, and synthesized containing N-halamine quaternary ammonium salt (HQAS) as antibacterial agent. Dimethylaminoethyl methacrylate (DMAEMA) as pH-responsive ...
