Abstract

Tyrosine hydroxylase is studied in terms of adsorption behaviour on gold surfaces and various passivating layers. Results reveal differences in layer formation, where mercaptoundecanoic acid-coated gold shows the best potential in terms of adsorbed mass. Nanoparticles with this coating are subsequently tested for enzymatic activity, which remains at attenuated levels.
