Chitosan based metal-chelated copolymer nanoparticles: Laccase immobilization and phenol degradation studies
(Elsevier Sci Ltd, 2017)Immobilization improves the stability and reusability of enzymes. In this study, laccase, which is a green biocatalyst, was immobilized onto Cu (II)-chelated chitosan nanoparticles via adsorption and successfully applied ... -
Chitosan-grafted poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) membranes for reversible enzyme immobilization
(Wiley, 2007)Epoxy group-contain g poly(hydroxyethyl methacrylate/glycidyl methacrylate), p(HEMA/GMA), membrane was prepared by UV initiated photopolymerization. The membrane was grafted with chitosan (CH) and some of them were chelated ... -
The chordae tendineae of the heart in chicken
(Blackwell Verlag Gmbh, 2004)In this study, the chordae tendineae of 10 adult chickens have been investigated by means of scanning electron microscopy (SEM). It has been observed that the diameter of the collagen fibrils on the left side of the heart ... -
