Semi-interpenetrating network of polyethylene glycol and photocrosslinkable chitosan as an in-situ-forming nerve adhesive.
An ideal adhesive for anastomosis of severed peripheral nerves should tolerate strains imposed on rejoined nerves. We use blends of photocrosslinkable 4-azidobenzoic acid-modified chitosan (Az-C) and polyethylene glycol (PEG) as a new in-situ-forming bioadhesive for anastomosing and stabilizing the injured nerves. Cryo-scanning electron microscopy suggests that the polymer blends form a semi-in...
متن کاملSorption and Drug Release Studies from Semi-interpenetrating Polymer Networks of Chitosan and Xanthan Gum
Hydrogels are crosslinked three-dimensional hydrophilic polymer networks capable of retaining a significant amount of water within their structures, and swell without dissolving in water.1 A hydrogel is formed when an organic polymer (natural or synthetic) is crosslinked via covalent, ionic, or hydrogen bonds to create a three-dimensional structure.2 Recently, much work has been carried out on ...
متن کاملChitosan-acryl amide grafted polyethylene glycol interpenetrating polymeric network for controlled release studies of Cefotaxime
The aim of this present study was to develop a pH sensitive interpenetrating polymeric network (IPN) hydro gels (HG) based on chitosan-acryl amide-grafted-poly ethylene glycol (CTS-AM-PEG) followed by hydrolysis that are cross-linked with glutaraldehyde (GA). Cefotaxime is an antibiotic drug was successfully loaded in these IPNHG’s. The HGs formed were characterized by Fourier transform infrare...
متن کاملSynthesis and Characterization of Biodegradable Semi-Interpenetrating Polymer Networks Based on Star-Shaped Copolymers of ɛ-Caprolactone and Lactide
In this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. The polymers were characterized by nuclear magnetic resonance (NMR) spectrometry, fourier transform infrared spectroscopy (F...
