1. An in-vivo device comprising:

  • a sampling chamber able to store a sample of a body lumen substance;

    a first opening to allow said body lumen substance to enter said chamber from the body lumen;

    a gate able to close and open said first opening of said sampling chamber;

    a second opening to allow said body lumen substance to exit said chamber to the body lumen;

    a first, flexible conductive plate able to repel from or attract to a second conductive plate when substantially equal or opposing current, respectively, is supplied to said first and second conductive plates, wherein said first and second conductive plates are located within said sampling chamber;

    a power source to supply said current to said first and second conductive plates;

    a first well formed when said first and second conductive plates are repelled from each other, said first well comprising a first reagent; and

    a second well formed when said first and second conductive plates are repelled from each other, said second well comprising a second reagent,wherein said sample is able to advance from said first well to said second well when said supplied current becomes opposing current in said first well while in said second well the current becomes substantially equal;

    wherein said in-vivo device is a swallowable capsule.
