A portable device for nucleic acid quantification powered by sunlight, a flame or electricity

A decentralized approach to diagnostics can decrease the time to treatment of infectious diseases in resource-limited settings, yet most modern diagnostic tools require stable electricity and are not portable. Here, we describe a portable device for isothermal nucleic acid quantification that can operate with power from electricity, sunlight or a flame, and that can store heat from intermittent energy sources for operation when electrical power...
