Novel hydrogel membrane based on copoly(hydroxyethyl methacrylate/p-vinylbenzylpoly(ethylene oxide)) for biomedical applications: Properties and drug release characteristics
(Wiley-V C H Verlag Gmbh, 2005)
The aim of this study was to synthesize and characterize a novel biocompatible polymeric membrane system and demonstrate its potential use in various biomedical applications. Synthetic hydrogels based on poly(hydroxyethyl ...
Ethylenediamine grafted poly(glycidylmethacrylate-co-methylmethacrylate) adsorbent for removal of chromate anions
(Elsevier Science Bv, 2005)
The removal of chromate anions (CrO42-) from aqueous solutions under different experimental conditions using cross-linked poly(glycidylmethacrylate-co-methylmethacrylate), poly(GMA-co-MMA), adsorbent was investigated in ...
Immobilization of Candida rugosa lipase onto spacer-arm attached poly(GMA-HEMA-EGDMA) microspheres
(Elsevier Sci Ltd, 2005)
Epoxy group-containing poly(GMA-HEMA-EGDMA) microspheres were prepared by suspension polymerisation. The epoxy groups of the poly(GMA-HEMA-EGDMA) microspheres were used for the covalent attachment of Candida rugosa lipase ...
Selective recovery of mercury by Procion Brown MX 5BR immobilized poly(hydroxyethylmethacrylate/chitosan) composite membranes
(Elsevier Science Bv, 2002)
Metal chelating membranes have advantages as adsorbents in comparison to conventional microspheres or beads because they are not compressible and they considerably eliminate internal diffusion limitations. The aim of this ...
Reversible immobilization of urease onto Procion Brown MX-5BR-Ni(II) attached polyamide hollow-fibre membranes
(Elsevier Sci Ltd, 2002)
Urease was immobilized onto Procion Brown MX-5BR attached and Ni(II) incorporated microporous polyarnide hollow-fibre membrane via adsorption. Urease immobilization onto the polyamide hollow-fibre membrane from aqueous ...
Congo Red attached monosize poly(HEMA-co-MMA) microspheres for use in reversible enzyme immobilisation
(Elsevier Science Sa, 2002)
Monosize and non-porous poly(2-hydroxyethylmethacrylate-co-methylmethacrylate) (poly(HEMA-co-MMA)), microspheres were prepared by dispersion polymerisation of HEMA and MMA in an ethanol-water medium in the presence of an ...
Poly(hydroxyethyl methacrylate) membranes: As a hydrogel support for use in immobilized metal affinity chromatography
(Wiley-V C H Verlag Gmbh, 2003)
Lysozyme adsorption onto a dye ligand (Procion Red HE-3B) immobilized and Cu(II) incorporated poly(2-hydroxyethylmethacrylate) (pHEMA) membrane were investigated. The membranes were prepared by UV initiated photopolymerization ...
Biosorption of heavy metal ions on immobilized white-rot fungus Trametes versicolor
(Elsevier, 2003)
Trametes versicolor mycelia were immobilized in carboxymethylcellulose, CMC, beads via entrapment, and the bead containing immobilized fungus spores were incubated at 30 degreesC for 3 days to attain uniform growth on the ...
Ca-alginate as a support for Pb(II) and Zn(II) biosorption with immobilized Phanerochaete chrysosporium
(Elsevier Sci Ltd, 2003)
The basidio spores of Phanerochaete chryosporium were immobilized in alginate gel beads, and the immobilized spore containing alginate beads were incubated for the growth of fungus. The biosorption of Pb2+ and Zn2+ ions ...
Immobilization of urease via adsorption onto L-histidine-Ni(II) complexed poly(HEMA-MAH) microspheres: Preparation and characterization
(Elsevier Sci Ltd, 2005)
Poly(2-hydroxyethyl methacrylate-co-N-methacryloly-L-histidinemethylester) poly(HEMA-MAH) microspheres was prepared via suspension polymerization. L-Histidine groups of the poly(HEMA-MAH) microspheres were then chelated ...
