This project will develop an ultrafast biosensor platform for in-situ detection of multiple contaminants (e.g., MIB, geosmin, PFAS, ammonia, nitrate, phosphate) in water by incorporating pattern recognition algorithms. For water utility companies, typical analyses of these contaminants require the transportation of water samples to a lab and is also expensive and labour intensive. Quick turnaround time from sampling to analytical result is a further unmet challenge where contamination of water supplies is suspected. Low-cost carbon sensor electrodes with properties of enhanced electron transfer and surface area will be derived from food wastes and fabricated using patented flexographic printing. They will generate characteristic electrochemical signals upon interaction with various contaminants in water that are distinct from those caused by non-specific adsorption. This will provide an essential step towards label free, direct, and easy-to-use in situ monitoring devices.

该项目将开发一种超快生物传感器平台，用于现场检测多种污染物（例如，MIB，土臭素，PFAS，氨，硝酸盐，磷酸盐）在水中的模式识别算法。对于自来水公司来说，这些污染物的典型分析需要将水样运输到实验室，而且成本高昂且劳动密集。在怀疑供水受到污染的情况下，从取样到分析结果的快速周转时间是另一个未得到满足的挑战。具有增强电子转移和表面积特性的低成本碳传感器电极将来自食物垃圾，并使用专利柔性版印刷制造。它们在与水中的各种污染物相互作用时会产生特征电化学信号，这些信号与非特异性吸附引起的信号不同。这将为实现无标签、直接和易于使用的原位监测设备迈出重要一步。
