The influence of the morphology of ethylene glycol dimethacrylate-hydroxyethyl methacrylate copolymer [poly(EGDMA-co-HEMA)] base support to obtain different Fe(3+)-containing sorbents and their properties in retention of O-phosphothreonine [Thre(P)] is examined in this paper. Three base supports poly(EGDMA-co-HEMA) (I-III) were obtained using

Two activated matrices have been developed to determine whether immobilization chemistry can be used to orient proteins on a support. Restriction endonuclease EcoRI from Escherichia coli RY13 (E.C.3.1.23.13) was used as a model in these studies. Thiol-activated Sephadex G-10 was

The polysaccharide ulvan, composed of sulphated rhamnose, glucoronic and iduronic acids was used to produce polymeric membranes by solvent casting. As ulvan is soluble in water, a cross-linking step was necessary to render the membrane insoluble in water and stable

Crosslinking of dermal sheep collagen (DSC) was accomplished using 1, 4-butanediol diglycidyl ether (BDDGE). At pH values > 8.0, epoxide groups of BDDGE will react with amine groups of collagen. The effects of BDDGE concentration, pH, time, and temperature were

Ongoing research has achieved much progress towards the development of new artificial skin substitute products. However, effective implant material for correcting full-thickness defects (such as those arising from extensive burns, tumor resection, hereditary or congenital defects and chronic wounds) has

Serious cartilage lesions (Outerbridge III, IV) may be successfully treated with a three-layered gradient scaffold made by magnesium-doped hydroxyapatite and type I collagen, manufactured through a bio-inspired process and stabilised by a reactive bis-epoxy (1,4-butanediol diglycidyl ether, BDDGE). Each layer

Linear polyethylenimine (lPEI, 25 kDa) nanoparticles' (LPN) series was synthesized by varying percentage of cross-linking with 1,4-butanediol diglycidyl ether (BDE) and their size, surface charge, morphology, pDNA protection/release, cytotoxicity and transfection efficiency were evaluated. Synthesized nanoparticles (NPs) were spherical in

Calcification limits the long-term durability of xenograft glutaraldehyde (GA)-crosslinked heart valves. Previously, a study in rats showed that epoxy-crosslinked heart valves reduced lymphocyte reactions to the same extent as the GA-crosslinked control and induced a similar foreign-body response and calcification
