Laccase from two different source organisms, Myceliophthora thermophila and Trametes hirsuta, were subjected to chemical modification in solution by (i) two bifunctional reagents, ethylene-glycol-N-hydroxy succinimide (EGNHS) and glutaraldehyde and (ii) by the monofunctional citraconic anhydride. The untreated and chemically modified forms of both enzymes(More)
Aqueous ZnO nanoparticle dispersions interaction with a dioleoyl phosphatidylcholine (DOPC) monolayer is reported in this paper. ZnO-DOPC interactions were investigated using rapid cyclic voltammetry (RCV) by focusing on the effect of the interactions on the characteristics of the capacitance current peaks representing two potential induced phase(More)
HYPOTHESIS The activity of submicron sized titanium oxide (TiO2) particles towards biomembrane models is coupled to their charge carrying capacity and their primary particle size. EXPERIMENTS Electrochemical methods using a phospholipid layer on mercury (Hg) membrane model have been used to determine the phospholipid monolayer activity of TiO2 as an(More)
