Enzyme-magnetic nanoparticle conjugates as a rigid biocatalyst for the elimination of toxic aromatic hydrocarbons

An enzyme-magnetic nanoparticle conjugate is prepared via conjugation of Ni(2+) ions onto the surface of magnetic nanoparticles to interact with a six histidine-tagged enzyme. The catalytic properties and enzyme rigidification of the conjugates are more stable at high concentrations of aromatic hydr...
