Anisotropic polyvinyl alcohol hydrogel for cardiovascular applications.
Polyvinyl alcohol (PVA) is a hydrophilic polymer with various characteristics desired for biomedical applications and can be transformed into a solid hydrogel by physical crosslinking, using a low-temperature thermal cycling process. As with most polymeric materials, the mechanical properties of the resultant PVA are isotropic, as oppose to most soft tissues, which are anisotropic. The objectiv...
متن کاملSynthesis and Characterization of an Enzyme Mediated in situ Forming Hydrogel Based on Gum Tragacanth for Biomedical Applications
Background: The excellent biocompatibility, biodegradability and biological properties of the hydrogels, fabricated using natural polymers, especially polysaccharides, are very advantageous for biomedical applications. Gum tragacanth (GT) is a heterogeneous highly branched anionic polysaccharide, which has been used extensively in food and pharmaceutical industries. Despite, its desirable prop...
متن کاملMicrogel, nanogel and hydrogel–hydrogel semi-IPN composites for biomedical applications: synthesis and characterization
Quaternary ammonium salt hydrogels from a cationic monomer, (3-acrylamidopropyl)-trimethylammonium chloride (APTMACl), in a variety sizes such as bulk, microand nanohas been prepared. The synthesis of microand nanogels were carried out in the microenvironment of water-in-oil microemulsions using two types of surfactants, namely, L-αphosphatidylcholine (lecithin) and dioctyl sulfosuccinate sodiu...
متن کاملThe effect of temperature and water absorption on enzymatic degradation of starch / polyvinyl alcohol blend film by α-Amylase
Thermoplastic starch (TPS) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure TPS materials. Further investigations on TPS: PVAblends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...
متن کاملImprovement of Starch Digestion Using α-Amylase Entrapped in Pectin-Polyvinyl Alcohol Blend
Polyvinyl alcohol (PVA) and pectin blends were used to entrap α-amylase (Termamyl) using glutaraldehyde as a cross-linker. The effect of glutaraldehyde concentration (0.25, 0.5, 0.75, 1.0, and 1.25%) on the activity of the immobilized enzyme and rate of enzyme released was tested during a 24 h period. Characteristics of the material, such as scanning electron microscopy (SEM), tensile strength ...
