Development of a hydrogel based water quality monitoring device

该项目的主要目标是开发一种可与商用水处理设备集成的快速水质监测设备。特别是，该项目的关键里程碑将是：(I)设计一种可以吸收100毫升水的设备(根据美国环保局的要求)，并同时浓缩和检测大肠杆菌，作为一个基于为流动水包开发的酶基质化学的综合系统；(Ii)制造该设备；(Iii)探索将该设备与水处理单元集成的可能机制，以便与行业合作伙伴一起实时监测水质。通过使用定制设计的柱塞管组件和内置过滤器(孔径为0.45微米)，可以同时浓缩和检测受污染水样中的大肠杆菌。柱塞管组件将

The key objective of this project is to develop a rapid water quality monitoring device that can be integrated with commercially available water treatment units. In particular, the key milestones for the project would be: (i) To design a device that could take 100 mL of water (as per US EPA requirement), and concentrate and detect E. coli simultaneously as an integrated system based on the enzymatic substrate chemistry developed for Mobile Water Kit (MWK); (ii) To fabricate the device; (iii) To explore possible mechanisms to integrate the device with the water treatment units for real-time monitoring of water quality with the industry partner. The simultaneous concentration and detection of E. coli in contaminated water samples can be achieved by using a custom designed plunger-tube assembly with a built-in filter (0.45 µm pore size). Plunger-tube assembly would
