Use of chemically modified poly( ethylene terephthalate)-g-(acryl amide) fibers for α-amylase immobilization
(European Polymer Federation, 2007)
Acryl amide grafted Poly(ethylene terephthalate) (AAm-g-PET) fiber was used for covalent coupling of alpha-amylase. The amide groups of Poly(acryl amide) were converted to the amine groups by Hofmann degradation reaction. ...

(WILEY, 2020)
kappa-Carrageenan-graft-poly(dimethylaminoethyl methacrylate) (CRG-g-PDMA) was synthesized via free-radical copolymerization under microwave irradiation.C-13-Nuclear magnetic resonance spectroscopy (C-13-NMR), fourier-transform ...
Procion Brown MX-5BR attached and Lewis metals ion-immobilized poly(hydroxyethyl methacrylate)/chitosan IPNs membranes: Their lysozyme adsorption equilibria and kinetics characterization
(Pergamon-Elsevier Science Ltd, 2002)
Interpenetration networks (IPNs) in membrane form were synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan (pHEMA/chitosan) via UV-initiated photo-polymerization in the presence of an initiator alpha, ...
Pectin-conjugated magnetic graphene oxide nanohybrid as a novel drug carrier for paclitaxel delivery
(Taylor & Francis Ltd, 2018)
Recent studies have shown that graphene oxide (GO) drug carrier functionalized with biocompatible natural polymers lead to higher loading efficacy and better stability with diminished cellular toxicity. Pectin (PEC) is one ...
Aptamer-functionalized magnetic graphene oxide nanocarrier for targeted drug delivery of paclitaxel
(Elsevier Science Sa, 2018)
Targeted drug delivery has come out as a golden system owing to its capability to reduce side effects and increase efficacy. The application of graphene oxide (GO) based nanomaterials for targeted delivery has recently ...
Immobilization of Saccharomyces cerevisiae on to modified carboxymethylcellulose for production of ethanol
(Springer, 2011)
In this work, modified carboxymethylcellulose (CMC) was used as a new support material for production of ethanol. Crosslinked graft copolymers of CMC with N-vinyl-2-pyrrolidone (N-VP) were prepared in different grafting ...
Effect of spacer-arm and Cu(II) ions on performance of L-histidine immobilized on poly(GMA/MMA) beads as an affinity ligand for separation and purification of IgG
(Elsevier, 2006)
In this study, the beads were prepared from glycidiyl methacrylate (GMA) and methyl methacrylate (MMA) via suspension polymerization and, the used beads fractions were between 75 and 150 mu m. The epoxy groups of the beads ...
