The effect of polar copolymers in protein absorption on contact lenses on 2-Hydroxyethyl methacrylate(HEMA)
For the purpose of increasing the permeability to oxygen and equilibrium water content in contact lenses, polar copolymers with nonionic monomers such as 2-hydroxyethle methacrylate(HEMA) Is used. By adding the polar monomers to (HEMA), the permeability to oxygen and equilibrium with water content is increased and also the absorption of proteins on lens surface is changed. In this research, the...

متن کاملCharacterization of poly(2-Hydroxyethyl Methacrylate) Scaffolds for Tissue Engineering
Physical properties of scaffolds intended for myocardial tissue regeneration were studied. Mechanical properties and degradation rates were evaluated for degradable scaffolds composed of poly (2-hydroxyethyl methacrylate) (pHEMA) crosslinked with polycaprolactone (PCL). pHEMA copolymerized with tetraethylene glycol as a crosslinker served as a control. Fibroblast cells were used for cytotoxicit...
متن کاملPreparation and Characterization of Poly(2-hydroxyethyl methacrylate) and Castor Oil Based Uralkyds Interpenetrating Polymer Networks
There is a growing interest in the development polymers based on renewable resources1-2. Polyurethanes constitute a kind of materials that can vary from rubbery to glassy thermoplastics from linear polymers to thermoset. This versatility can be further controlled in terms of processing and composition to fulfil a great versatility that permit the manufacturing of products ranging from expanded ...
متن کاملFeedback-regulated paclitaxel delivery based on poly(N,N-dimethylaminoethyl methacrylate-co-2-hydroxyethyl methacrylate) nanoparticles.
pH-Sensitive poly(N,N-dimethylaminoethyl methacrylate (DMAEMA)/2-hydroxyethyl methacrylate (HEMA)) nanoparticles were prepared for the triggered release of paclitaxel within a tumor microenvironment. Tumors exhibit a lower extracellular pH than normal tissues. We show that paclitaxel release from DMAEMA/HEMA particles can be actively triggered by small, physiological changes in pH (within 0.2-0...
