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.
