Acquired · Zurich, Zurich · founded 2015 · 14 employees$127.5Kraised▾
Haelixa provides intelligent DNA-based tracing solutions allowing fluid/item tracking and parameter monitoring (temperature, light, pH, oxidants) to support the energy industry (underground exploration and monitoring), and ensure product authentication and quality control as well as liability management. The tracers are composed of DNA sequences encapsulated within invisible particles that can be mixed with any fluid and item, providing it with a unique fingerprint, which is easily identified and quantified at parts per trillion level (1 milligram per ton) with bio-analytics used in medicine and forensics. The use of DNA permits to generate as many distinct fingerprints as are needed as unlimited DNA sequences are available. The encapsulation improves DNA stability, providing resilience in harsh conditions. Both DNA and particles can be engineered to obtain tracers capable of determining temperature, pH, oxidant concentration, light intensity. The main applications of the technology currently are - Reservoir Monitoring (characterize and monitor oil or geothermal reservoirs by tracking the movement of fluids in the subsurface) and Product Authentication (transparent identification a
