Problem Statement

No way of knowing the food will give me food poisoning.

How do I know the food has gone bad? This is a common problem for every household when you have food left at room temperature for some time. Or are you worried about the food that you bought at the eatery might give you food poisoning? The problem is there's no on-site testing method to detect bacteria growing in the food.

Solution Statement

NanoSense - Portable kit to detect Salmonella

NanoSense, patented point-of-care (POC) device, detects Salmonella bacteria in food rapidly. It able to detect 3 types of pathogenic Salmonella specifically:

  • S. Typhi,
  • S. Enteritidis and
  • S. Paratyphi

These types of bacteria are the most common bacteria for foodborne diseases. Food samples, with traces of bacteria, meshed with water is all it needs for the on-site testing by inserting the chip into its low-cost portable reader.  NanoSense is an efficient rapid, sensitive, point-of-care detection system for foodborne pathogen as easy as glucose testing for the public and regulators.

Total Addressable Market
Almost 1 in 10 people in the world – fall ill after eating contaminated food and 420 000 die every year, resulting in the loss of 33 million healthy life years (DALYs). Children under 5 years of age carry 40% of the foodborne disease burden, with 125 000 deaths every year.
