Biosensors for PUBLIC Health

At Stemloop, we repurpose biology to empower people with the information they need to confidently make meaningful public, environmental, and community health decisions.

Laboratory Testing Does Not Scale

Traditional laboratory testing can take weeks and cost hundreds of dollars to get results. This is due to centralized testing infrastructure that requires sample transportation, complicated equipment, and technical expertise. These high costs and time delays are unacceptable for threats like pathogens, toxins, and chemical contaminants that require immediate answers.

Cell-free Biosensors

At Stemloop, we repurpose biological mechanisms to create sensors that function outside of a cell. These “cell-free” biosensors enable rapid, low-cost solutions for the on-site detection of pathogens and chemical contaminants. In contrast to laboratory testing, Stemloop’s cell-free biosensors can be scaled up and widely deployed for high-resolution public health surveillance.

Pathogen Detection

Our platform offers several advantages over other synthetic biology approaches. Leveraging our deep expertise in the development of easy-to-use cell-free biosensors, Stemloop is developing sensors that are highly modular, easily optimized, configured to specific technologies, and are available for our customers' point-of-use applications.
