Abstract

An important component in signal transmission in electrochemical biosensors is electrodes. A variety of methods can be used to prepare electrodes but, in general, use a screen-printing method that combines carbon-based conductive materials with the consideration of low cost, relatively easy fabrication process, and capable of being produced on a mass scale. From previous studies, electrodes with uniform texture and honeycomb structure can be produced. However, the electrode fabrication process is still done manually. This machine modification aims to improve the quality and quantity of the electrodes. CNC 3018 mini engraver can be modified and changed its function with prices ranging from $89 to $110. The electrodes for electrochemical biosensors have a fairly high repetition percentage of 2.6%. The total cost for modification is $128.15, so the print results using this machine produce uniformity of screen-printing results with a low-cost and easy fabrication process.
