In major part, traditional laboratory testing is centralized - typically involving special equipment, transporation, and technical expertise such that the process can be long-time and expensive. In situations that involve pathogens, toxins, and chemical contaminants - where immediate answers may be required - high costs and time delays are unacceptable. To address these issues, Stemloop is structured around development of cell-free biosensors: repurposing biological mechanisms to create sensors that function outside a cell. This approach offers situation of rapid, low-cost solutions for the on-site detection of pathogens and chemical contaminants.Further, Stemloops cell-free biosensors can be scaled up and widely deployed for high-resolution public health surveillance. In conditions involving pathogen detection, the firm's approach represents a number of advantages over other synthetic biology approaches. Leveraging the expertise of the firm's principals in development of easy-to-use cell-free biosensors, Stemloop is developing sensors that are highly modular, easily optimized, configured to specific technologies, and can be made available for point-of-use applications
