A method is described for fabrication of 7-barrelled microiontophoresis electrodes with a center barrel of platinum-coated tungsten. The electrodes require a minimum of expensive apparatus and can be fabricated in an hour or two. The electrodes have low recording impedance (typically 100 k omega and low resistance iontophoresis barrels (typically 20-50 M omega). Compared to electrodes with a micropipette recording barrel, these electrodes are practically noise-free and can pass ionotophoretic currents of up to 200 nA without an appreciable increase in recording noise.
本文描述了一种用于制造七管微离子透入电极的方法，其中心管为镀铂钨丝。该电极所需昂贵设备最少，一两个小时即可制造完成。这些电极具有低记录阻抗（通常为100 kΩ）和低电阻离子透入管（通常为20 - 50 MΩ）。与带有微吸管记录管的电极相比，这些电极几乎无噪声，并且能够通过高达200 nA的离子透入电流而记录噪声没有明显增加。
