Gates Foundation Award
7 November 2018
Professor Bruce Grieve will be working on a 'Biomimetic In-Field, IoT, "Sentinel" Fungal & Viral Sensor' for a Grand Challenges Gates Foundation award.
Bruce will develop a low-cost, stereo-printed sensor that mimics plant leaves and stems and can detect and signal the presence of live pathogens as an early warning system to help protect crops in low-resource settings.
Bruce and his team will demonstrate proof-of-concept of their approach in the laboratory by designing three dimensional sensors with specific patterns of cells and chemically-doped polymers to identify an ideal surface on which pathogenic fungal spores can grow and differentiate.
Incorporated sensor cells will be designed to detect the live pathogens and produce a detectable response, such as a visible density change, and results can be stored locally or transmitted wirelessly.
They will test different sensor designs for the detection of rust pathogens in wheat, and their approach can be adapted to detect multiple pathogens simultaneously, including viruses, as well as for human and livestock pathogens, and when deployed in the field can ultimately be linked to national surveillance systems.
