Claim 0:
1. A device, comprising:
a first plate and a second plate, wherein:
the first and second plates are movable relative to each other into an open configuration and a closed configuration,
each of the first and second plates respectively comprise an inner surface that has a sample contact area for contacting a fluid sample, and
at least one of the plates is flexible;

spacers that are fixed on at least one of the first and second plates and have a predetermined substantially uniform height; and
a first and a second electrode fixed to at least one of the first and second plates;
wherein in the open configuration, the first and second plates are partially or entirely separated apart to enable the fluid sample to be deposited on at least one of the first and second plates, wherein a spacing between the first and second plates is not regulated by the spacers; and
wherein in the closed configuration, which is configured after the fluid sample is deposited on at least one of the first and second plates in the open configuration, at least part of the fluid sample is compressed by the first and second plates into a layer of substantially uniform thickness and is substantially stagnant relative to the first and second plates, wherein the layer is confined by the inner surfaces of the first and second plates and is regulated by the spacers, and wherein the at least part of the sample is between the first plate and the second plate and the average spacing between the inner surfaces of the first and second plates is less than 200 μm.
