Caption

The special membrane used by the device is first coated with an HIV-specific antibody which captures HIV viruses. Then, gold and silver nanoparticles are bound to the captured HIV. With each of the steps, ions become progressively less able to reach electrodes. By measuring the resulting current, it is possible to determine the amount of virus that has been caught in the membrane.
