Biodegradable HEMA-based hydrogels with enhanced mechanical properties.
Hydrogels are widely used in the biomedical field. Their main purposes are either to deliver biological active agents or to temporarily fill a defect until they degrade and are followed by new host tissue formation. However, for this latter application, biodegradable hydrogels are usually not capable to sustain any significant load. The development of biodegradable hydrogels presenting load-bea...
متن کاملSwelling and Mechanical Properties of Modified HEMA- based Superporous Hydrogels
Superporous hydrogels (SPHs), based on poly(2-hydroxyethyl methacrylate) (PHEMA), were prepared by adding minute amounts of an ioncomplexable hydrophilic acrylic acid. PHEMA SPHs are generally strong, but their swelling is minimal. To improve the swelling, different poly(HEMA-coacrylic acid) hydrogels were polymerized and crosslinked, then physically treated with divalent calcium and trivalent ...
متن کاملBiodegradable stereolithography resins with defined mechanical properties
Solid Freeform Fabrication methods based on photopolymerization (e.g. stereolithography SLA, digital light processing DLP, two photon absorption TPA) offer the possibility to shape complex structures with high feature resolution and excellent surface quality. If these methods are to be used for applications in regenerative medicine, new photopolymers with defined functional and mechanical prope...
متن کاملMolecularly engineered p(HEMA)-based hydrogels for implant biochip biocompatibility.
The strategy of phospholipid-based biomimicry has been used to molecularly engineer poly(2-hydroxyethyl methacrylate) [p(HEMA)]-based hydrogels for improved in vitro and potential in vivo biocompatibility. Two methacrylate-based monomers, poly(ethylene glycol) (200) monomethacrylate (PEGMA) and 2-methacryloyloxyethyl phosphorylcholine (MPC), were incorporated at varying mole fractions of 0.0-0....
متن کاملBiodegradable Cellulose-based Hydrogels: Design and Applications
Hydrogels are macromolecular networks able to absorb and release water solutions in a reversible manner, in response to specific environmental stimuli. Such stimuli-sensitive behaviour makes hydrogels appealing for the design of ‘smart’ devices, applicable in a variety of technological fields. In particular, in cases where either ecological or biocompatibility issues are concerned, the biodegra...
