The electron transfer of redox-active sites of immobilised haemoglobin (Hb) has been studied by voltammetric experiments. The electrode surface was modified by nanoparticles (NPs) to make a suitable substrate for electric wiring of protein molecules and efficient electron transferring. Hence, the Hb/zinc oxide NPs/platinum electrode was prepared by chronoamperometric deposition of the NPs and immobilisation...
Using a simple hydrothermal method without surfactants and templates, different morphologies of titanium dioxide (TiO2) have been synthesised such as nanocubes, nanosheets and microspheres. The effects of the addition of hydrofluoric acid (HF) and hydrogen peroxide (H2O2) in the preparation of TiO2 were studied. It was found that more H2O2 may accelerate the formation of a spherical morphology and...
