On-site environmental DNA sensing with user-friendly test strips

生物体将它们的基因释放到环境中。该项目旨在开发世界上第一个用于这种环境DNA的现场便携式生物传感器。基于一种新的传感原理，它们将提供与目前基于实验室的技术相媲美的性能。它们将快速(&lt；1小时)、成本效益(&lt；每条1美元)和坚固耐用。项目成果将包括基于试管的测试，能够检测到1个DNA拷贝/微升和超轻试纸试纸，两者都具有肉眼读数。这些传感器在水测试中的应用将与澳大利亚的行业合作伙伴Biopoint共同开发。好处将包括加强对入侵害虫的保护，以及在没有实验室测试和样本后勤的情况下传播抗菌素耐药性。

Organisms shed their genes into the environment. This project aims to develop world-first field-portable biosensors for this environmental DNA. Based on a novel sensing principle, they will offer performance comparable with current laboratory-based techniques. They will be rapid (< 1 h), cost -effective (< $ 1 per strip) and robust. Project outcomes will include tube-based tests able to detect 1 DNA copy / microlitre and ultralight paper test strips, both with naked-eye readout. Applications of these sensors in water testing will be developed with an Australian industry partner Biopoint. Benefits will include strengthened protection against invasive pests and the spread of antimicrobial resistance without lab testing and sample logistics.
