A novel pH sensitive porous membrane carrier for various biomedical applications based on pHEMA/chitosan: Preparation and its drug release characteristics
(Wiley-V C H Verlag Gmbh, 2003)
The synthetic hydrogels based on pHEMA have been widely studied and used in biomedical fields. Numerous techniques exist for entrapment of drugs or proteins in the hydrogels. The suitable biomaterials for biomedical ...
Dye-ligand immobilized IPNs membrane for removal heavy metal ions
(Wiley-V C H Verlag Gmbh, 2003)
We have developed a novel approach to obtain high metal sorption capacity utilizing a membrane containing chitosan and an immobilized reactive dye (i.e. Reactive Yellow-2). The composite membrane was characterized by SEM, ...
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 ...
Separation of human-immunoglobulin-G from human plasma with L-histidine immobilized pseudo-specific bioaffinity adsorbents
(Marcel Dekker Inc, 2002)
The pseudo-biospecific affinity ligand L-histidine immobilized poly(2-hydroxyethylmethacrylate) (PHEMA) in spherical form (100-150 mum in diameter) was used for the affinity chromatographic separation of human-immunoglobulin-G ...
Cadmium and mercury uptake by immobilized Pleurotus sapidus
(Scientific Technical Research Council Turkey, 2002)
Pleurotus sapidus basidiospores immobilized onto Ca-alginate beads were used for the removal of cadmium and mercury ions from aqueous solutions. The biosorption of Cd(II) and Hg(II) ions on the alginate beads and both ...
