Abstract
The feasibility of allatostatin direct immunoassays based on capacitan ce measurements with TiO2 modified electrodes is presented. The low co nductance and good dielectric properties of the TiO2 substrate insure good sensitivity. This was proven by a capacitance decrease of about 1 nF cm(-2) for a 3000 times diluted insect serum sample. The simple co nstruction and the miniaturisation possibility advocate this structure for direct immunoassay. (C) 1997 Elsevier Science S.A.
