The dispersibility of bio-molecules such as lecithins on the surface of ZnO nanowires are investigated for biosensor applications.Lecithins can be absorbed on an as-synthesized ZnO nanowire surface in the form of sub-micro sized clusters,while scattering well on those annealed under oxygen atmosphere.Wettability analysis reveals that the as-synthesized ZnO nanowires bear a super-hydrophobic surface,which convents to superhydrophilic after oxygen annealing.First-principles calculations indicate that the adsorption energy of ZnO with water is about 0.2 eV at a distance of 2(A) when it is superhydrophilic,suggesting that lecithin can be absorbed on the hydrophilic surface stably at this distance and the bio-affinity can be enhanced under this condition.
