Highly antibacterial materials constructed from silver molybdate nanoparticles immobilized in chitin matrix

摘要: Abstract Chitin gel-membranes (CGM), which fabricated directly from chitin solution in NaOH/urea aqueous system at low temperature, were applied for situ synthesis of Ag 2 Mo O 7 nanoparticles to obtain hybrid nanomaterials. The microporous structure CGM wet state was served as reaction chambers synthesize the nanoparticles. and properties nanocomposite membranes characterized with X-ray diffraction, thermal gravimetric analysis, scanning electron microscopy Fourier transform infrared spectroscopy. results indicated that film dry showed mesopore structure, average size 10 nm dispersed uniformly along wall immobilized matrix. There a strong interaction between chitin, porous matrix played an important role immobilization inorganic Moreover, /chitin exhibited significantly antibacterial activity even tested microbial broth. It could be explained DNA lost its replication ability protein became inactivated due associating + . composite membrane would ideal candidate tissue engineering wound dressing application. This work provided novel “green” pathway fabrication nanoparticle/polymer materials, having great potentials biomaterial field.
