Biocompatible magnetic nanoparticles grafted by poly (carboxybetaine acrylamide) for enzyme immobilization
L Zhang, Y Du, J Song, H Qi - International journal of biological …, 2018 - Elsevier
Herein, the zwitterionic material poly (carboxybetaine acrylamide) was grafted onto iron
oxide to obtain biocompatible magnetic nanoparticles Fe 3 O 4-pCBAA which were
employed to immobilize enzymes. The nanocomplxes Fe 3 O 4-pCBAA were characterized
using scanning electron microscopy (SEM), dynamic light scattering (DLS), zeta potential,
Fourier transform-infrared (FT-IR) spectra and energy dispersive X-ray spectrometry (EDX).
The urease as a model enzyme was immobilized with the novel supports and the properties …
