Resumen:
A device is described which allows controlled application of non-ionized drugs and proteins to discrete areas of the surface of muscle cells. It consists of two concentric micro-pipettes arranged so that the tip of the inner one, which is attached to a coil moving in a magnetic field, plugs from the inside the tip of the outer pipette which contains the drug solution. The aperture of the tap can be controlled accurately by energizing the coil with current pulses as short as 50 msec. Experiments are briefly described in which the operation of the micro-tap was tested by applying acetylcholine to the end-plates of frog muscle. © 1967.
