NRS Nanotube Edge Biosensors utilizes carbon nanotube field-effect transistors to detect specific biomarkers secreted from common foodborne pathogens in real time, with very high accuracy to assist in the detection of food spoilage. Food spoilage is a large scale global problem and part of the global nutrition security challenge that NRS has set out to improve. Roughly one third of the food produced in the world for human consumption every year — approximately 1.3 billion tonnes — gets lost or wasted. Food losses and waste amounts to roughly US$ 680 billion in industrialized countries and US$ 310 billion in developing countries. The biosensors utilization of direct electronic detection voids the need to use optics and light sources, which, in turn, allows for low form-factor devices to be developed. In addition, Nanoscale dimensions allow for massively multiplexed assays resulting in a high throughput bio-sensing platform.
