Investigating reproducible and reliable electrode fabrication for water quality testing

可重复和可靠的电极制造的水质传感器是必不可少的，以确保准确，低成本，一致的测量。FREDsense技术公司开发了一种新型的低成本系统，用于使用工程细菌检测水样中的痕量污染物。细菌产生可量化的电信号，表明水样中化合物的含量。细菌的电输出既快速又敏感，可以被电极检测到，使它们成为生物传感器系统的重要组成部分。因此，一种可靠、快速、低成本的制造方法对于FREDsense系统在当前水监测工作流程中的成功实施至关重要。本研究将使用溅射沉积方法确定优化的电极参数。

Reproducible and reliable electrode manufacturing for water quality sensors is essential to ensuring accurate,low cost, consistent measurements. FREDsense Technologies Corp. has developed a novel, low cost system forthe detection of trace levels of contaminants in water samples using engineered bacteria. The bacteria produce aquantifiable electrical signal that indicates the amount of a compound present in the water sample. Theelectrical output from the bacteria is both fast and sensitive and is detected by the electrodes, making them anessential part of the biosensor system. Therefore, a method to fabricate them reliably, quickly and at a low costare essential for the successful implementation of the FREDsense system into current water monitoringworkflows. This study will determine the optimized electrodes parameters using a sputter deposition approachto their manufacture.
