Immobilization of Laccase from Trametes hirsuta onto CMC Coated Magnetic Nanoparticles
In this study, Fe3O4/CMC magnetic nanoparticles were synthesized through co-precipitation method. Afterward, laccase from Trametes hirsuta was immobilized onto Carboxymethyl cellulose (CMC)-coated magnetic Fe3O4 nanoparticles by covalent bonding between carboxyl groups of carboxymethyl cellulose and amine group of laccases. Also, the...
متن کاملSimple and Rapid Immobilization of Firefly Luciferase on Functionalized Magnetic Nanoparticles; a Try to Improve Kinetic Properties and Stability
We expressed and purified a recombinant P. pyralis luciferase with N-terminal His-tags. The silanized Ni or Cu-loaded magnetic particles were prepared and used to assemble the His-tagged P. pyralis luciferase. This enzyme immobilized on functionalized magnetic nanoparticles (MNPs) via electrostatic interactions of His-tag with Ni2+/Cu2+ ions on the surface of MNPs using si...
متن کاملMagnetic nanoparticle immobilized N-propylsulfamic acid: The efficient, green and reusable nanocatalyst for the synthesis of substituted coumarins
N-Propylsulfamic acid supported onto magnetic Fe3O4 nanoparticles (MNPs-PSA) was investigated as an efficient and magnetically recoverable catalyst for the one-pot synthesis of substituted coumarins from the reaction of coumarin with variety aromatic aldehydes in high to excellent yield at room temperature under solvent-free conditions. The magnetic nanocatalyst can be readily recovered easily ...
متن کاملCu(I) nanoparticles immobilized onto Poly (Vinylpyridine-N-N-Methylenebisacrylamide-Acrylicacid) as a new, efficient and recyclable catalyst for the regioselective synthesis of 1, 2, 3-Triazoles via click reaction in water
Poly (vinylpyridine-N-N-methylenebisacrylamide-acrylicacid) (2-VP-MBAm-AA) was prepared from the reaction of TiO2-methacryloxypropyltrimethoxysilane (TiO2-MAPTMS) with 2-vinylpyridine, methylenbisacrylamide (MBAm) and tert-butyl acrylate (t-BuA). Subsequently (2-VP-MBAm-AA) was reacted with CuI to give the Cu(I) NPs supported onto the above polym...
