Abstract A series of composite sorbents based on the rigid macroporous polyhydroxyethyl methacrylate (HEMA)-based support filled with soft dextran gel was prepared. The affinity dyes Cibacron Blue and Remazol Brilliant Blue were then immobilized on both the original HEMA and the composite (HEMA-D) sorbents. The properties of HEMA and HEMA-D sorbents,

Adsorption of Bovine Serum Albumin onto Surface-Modified Polyhydroxyethyl Methacrylate Beads
Journal of Biomaterials Applications, 2003The adsorption of bovine serum albumin (BSA) onto poly(2-hydroxyethyl methacrylate) (PHEMA) beads modified by using the pair of hexamethylene diisocyonate–suberic acidbis-N-hydroxy succinimide has been studied as a function of protein concentration and adsorption time.

A series of polymers system based on poly(butyl methacrylate) (PBMA) and poly (hydroxyethyl methacrylate) semi-interpenetrating polymer networks (semi-IPN) (PBMA/ PHEMA = 70/30 by weight) have been attained by a sequential polymerization method using divinylbenzene (DVB) as cross-linking agent.

International Ophthalmology, 2017
Artificial cornea is the effective treatment option for corneal blindness. One of the challenges with the artificial cornea is limited, or no tissue integration necessitates reimplantation due to necrosis or corneal melting. We propose here a new formulation approach for core-skirt incorporating graphite in the outer skirt region to improve cell ...

Abstract Three classes of water may exist in certain hydrogels. We have previously labeled these as X water (bulk water), Z water (bound water) and Y water (intermediate forms we call interfacial water). Bulk gel conductivity data for poly (2-hydroxyethyl methacrylate) (PHEMA) were obtained.

Viscoelasticity of Calf Hide Impregnated with Radiation-Polymerized Polyhydroxyethyl Methacrylate
1986In order to combine the desirable properties of synthetic polymers (elasticity and water, chemical, and biological resistance) with those of animal hide (strength, flexibility, and dyability), composites can be formed between the two types of material. Actually, adding materials to hide has long been an aspect of traditional leathermaking, usuaslly to ...

The purpose of the study was the evaluation of 2-polyhydroxyethyl methacrylate (2-P-HEMA) for endovascular liquid embolization of experimental side-wall aneurysms following stent protection in a canine model. The swelling behaviour and polymerization characteristics of 2-P-HEMA in different solutions were investigated in vitro.

Abstract Magnetic nanoparticles (Fe3O4) coated with polyethylene glycol (PEG), (Fe3O4/PEG), were synthesized by chemical co-precipitation of Fe2+/Fe3+ salts by aqueous ammonia in PEG solution. Radiation polymerization of 2-hydroxyethyl methacrylate (HEMA) monomer solution onto Fe3O4/PEG was performed at different doses to synthesize (Fe3O4/PEG)-pHEMA,

The nanofiber membranes based on native starch are prone to swelling or dissolution after contact with water, and the fragile starch membranes, due to the aging of molecular chains, are unsuitable for medical dressings. Herein, the hydrophobic polyhydroxyethyl methacrylate (PHEMA) branches in different ratios were grafted onto high amylose corn starch (
