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 کاملSingle Macromolecule Nanomechanical Design: Poly(2-hydroxyethyl methacrylate-g-ethylene glycol) Graft Copolymers of Varying Architecture
With the advent of nanotechnology, the behavior of individual polymer chains is increasingly being studied due to their potential to act as molecular springs, switches, sensors, shock absorbers, and motors. Single molecule force spectroscopy (SMFS) or “tensile testing” is a powerful technique that is fast enabling rational nanomechanical design of synthetic polymers for such applications.1-3 Re...
متن کاملMacroporous hydrogels based on 2-hydroxyethyl methacrylate. Part II. Copolymers with positive and negative charges, polyelectrolyte complexes.
Crosslinked macroporous hydrogels based on 2-hydroxyethyl methacrylate (HEMA)-[2-(methacryloyloxy)ethyl]trimethylammonium chloride (MOETACl) copolymer, HEMA-MOETACl-methacrylic acid (MA) terpolymer, and on a polyelectrolyte complex of HEMA-MA copolymer with poly(MOETACl) were prepared. All the hydrogels were prepared in the presence of fractionated sodium chloride particles. The hydrogels were ...
متن کاملFabrication and Evaluation of 2-Hydroxyethyl Methacrylate-co-Acrylic Acid Hydrogels for Sustained Nicorandil Delivery
Purpose: To fabricate and evaluate oral 2-hydroxyethyl methacrylate-co-acrylic acid hydrogels as a drug delivery system for sustained release of nicorandil. Methods: HEMA-co-AA hydrogels using different monomer concentrations were prepared by free radical polymerization. N, N-methylene bis acrylamide (MBA) was used as crosslinker and potassium persulphate (KPS) as initiator. Nicorandil (20 mg) ...
