The manufacture of a metal film electrode on a multibarrelled micropipette is described. Gold film is sputtered onto the external surface of a multibarrelled micropipette and subsequently insulated. Gold film exposed at the tip operates as an extracellular recording microelectrode and the micropipettes may be used for iontophoresis of drugs or marker dyes. This method may be used to produce electrodes with increased numbers of iontophoresis channels at the tip without altering the low impedance and good recording characteristics of the metal film (recording) electrode.
本文描述了在多管微电极上制造金属薄膜电极的方法。将金膜溅射在多管微电极的外表面，随后进行绝缘处理。尖端暴露的金膜用作细胞外记录微电极，而微电极可用于药物或标记染料的离子电泳。该方法可用于制造尖端具有更多离子电泳通道的电极，同时不改变金属薄膜（记录）电极的低阻抗和良好记录特性。
