1. A system for analyzing membranous samples, comprising:
- a carrier with a shelf structure, the shelf structure having an aperture;
first and second fluid compartments, separated by the carrier, and fluidically connected to one another, in the absence of a membranous sample, via the aperture;
a membranous sample, selected from the group consisting of cells, organelles, and vesicles, sealed across the aperture, wherein the seal has an electrical resistance of greater than about 1 GΩ
; and
first and second electrodes, in electrical contact with the first and second fluid compartments, respectively, wherein the first and second electrodes are adapted to apply and/or measure at least one of an electrical potential and a current from at least a portion of the membranous sample sealed across the aperture.
