An electrode in an apparatus and method for analysis of cellular biological material via non-linear dielectric spectroscopy for the application of an AC potential, comprises silver/silver halide. In use, an AC electrical potential is applied at one or more discrete frequencies to biological material, a response determined at one or more frequencies substantially absent from the applied AC potential, and the response of the biological material compared with a stored determinand associated with the cellular biological material. The electrode specified gives substantially reduced background harmonic generation (noise). |
