Preparation of polyphosphazene hydrogels for enzyme immobilization.
We report on the synthesis and application of a new hydrogel based on a methacrylate substituted polyphosphazene. Through ring-opening polymerization and nucleophilic substitution, poly[bis(methacrylate)phosphazene] (PBMAP) was successfully synthesized from hexachlorocyclotriphosphazene. By adding PBMAP to methacrylic acid solution and then treating with UV light, we could obtain a cross-linked...
متن کاملPreparation of hydrogel microspheres by coacervation of aqueous polyphosphazene solutions.
A new method of preparing ionically cross-linked polyphosphazene hydrogel microspheres which enables effective control over microsphere size distribution has been developed. The synthesized microspheres can be used in protein delivery and, especially, as vaccine delivery vehicles. A new technique utilizes the ability of aqueous solutions of poly[di(carboxylatophenoxy)phosphazene] (PCPP) to form...
متن کاملInvestigating DNA hydrogels as a new biomaterial for enzyme immobilization in biobatteries.
We report the usage of DNA hydrogels for enzyme entrapment in an enzymatic biobattery. With the recent advancements in DNA nanotechnology, the incorporation of DNA materials to bioelectrocatalytic electrodes holds great promise to improve the performance of bioelectrocatalysis-based devices.
متن کاملPreparation of a Cu(II)-PVA/PA6 Composite Nanofibrous Membrane for Enzyme Immobilization
PVA/PA6 composite nanofibers were formed by electrospinning. Cu(II)-PVA/PA6 metal chelated nanofibers, prepared by the reaction between PVA/PA6 composite nanofibers and Cu2+ solution, were used as the support for catalase immobilization. The result of the experiments showed that PVA/PA6 composite nanofibers had an excellent chelation capacity for Cu2+ ions, and the structures of nanofibers wer...
متن کاملPreparation of Coaxial-Electrospun Poly[bis(p-methylphenoxy)]phosphazene Nanofiber Membrane for Enzyme Immobilization
A core/sheath nanofiber membrane with poly[bis(p-methylphenoxy)]phospha-zene (PMPPh) as the sheath and easily spinnable polyacrylonitrile (PAN) as the core was prepared via a coaxial electrospinning process. Field-emission scanning electron microscopy and transmission electron microscopy were used to characterize the morphology of the nanofiber membrane. It was found that the concentration of t...
