Analytical or monitoring apparatus and method
First Claim
1. A method of analysing a metabolic state of cellular biological material, said method comprising applying an AC electric potential at one or more discrete frequencies to a sample of the cellular biological material, and determining a response at one or more response frequencies which were substantially absent from the applied AC potential, said one or more response frequencies resulting from a combination of the applied frequency or frequencies.

Abstract
Cellular biological material (such as living tissue) is analysed or monitored by applying an AC electrical potential across the biological material so as to produce a nonlinear dielectric spectrum, and obtaining a detectable signal corresponding to the resulting spectrum. The potential is of a first frequency and the measured response at one or more second frequency substantially not overlapping with the first frequency.
