Growing concerns about the quality and safety of water and beverages, present an immediate need for sensing devices that are portable, easy to use, and inexpensive. Use of existing laboratory instruments such as atomic absorption spectrometry, inductively coupled plasma-mass spectroscopy, and x-ray fluorescence for heavy metal testing is expensive, laborious and time-consuming. The I-Corps team has developed a portable electrochemical chemical sensing system (E-Tongue) that mimics the human gustatory system using disposable electrochemical sensors combined with pattern recognition techniques for detecting heavy metals. The rapid, user-friendly, low cost, and portable E-Tongue will lend itself readily for on-site testing of water and beverages. The economic impact of this technology is expected to be quite significant since this technological platform will address the large market for water and beverage analysis instrumentation.The I-Corps team has developed an E-Tongue prototype for toxic heavy metal detection. It consists of a compact potentiostat device with disposable screen printed electrodes. The E-Tongue prototype will be trained to identify target elements as well as predict their concentrations in water and different beverage matrices containing buffer solutions. The E-Tongue demonstrations will initially focus on detecting lead, cadmium, mercury, and arsenic. The detection capabilities will be expanded in the future to include other heavy metals including chromium, nickel, copper, and zinc. The E-Tongue performance will be tested and evaluated by comparing it with results obtained using standard analytical methods. Several performance parameters such as selectivity, limit of detection, repeatability, precision and accuracy will be determined

人们对水和饮料的质量和安全性的关注日益加剧，提出了对便携式，易于使用且价格便宜的感应设备的即时需求。使用现有的实验室仪器，例如原子吸收光谱法，电感耦合的血浆质量光谱和X射线荧光进行重金属测试，这是昂贵，费力且耗时的。 I-Corps团队已经开发了一种便携式电化学化学传感系统（E-tongue），该系统使用一次性电化学传感器结合了检测重金属的模式识别技术，模仿了人类味道系统。快速，用户友好，低成本和便携式电子丁字管将很容易地进行水和饮料的现场测试。预计该技术的经济影响将非常重要，因为该技术平台将解决较大的水和饮料分析仪器市场。I-Corps团队已经开发了用于有毒重金属检测的电子串联原型。它由带有一次性丝网印刷电极的紧凑型电静脉设备组成。电子丁格原型将进行训练，以识别目标元素，并预测其在水中的浓度和含有缓冲溶液的不同饮料矩阵。 电子丁格演示最初将集中于检测铅，镉，汞和砷。未来的检测能力将扩大，以包括其他重金属，包括铬，镍，铜和锌。电子串行性能将通过将其与使用标准分析方法获得的结果进行比较来测试和评估。将确定几个性能参数，例如选择性，检测限，可重复性，精度和准确性
