PositiveID Corporation™ (OTCBB: PSID) is an emerging growth company and developer of biological detection systems for America's homeland defense industry as well as rapid medical testing. PositiveID is focused on the development of microfluidic systems for the automated preparation of and performance of biological assays in order to detect biological threats at high-value locations, as well as analyze samples in a medical environment.
In May 2011, PositiveID acquired California-based MicroFluidic Systems, founded in 2001, which specializes in the development and production of automated instruments for detecting and processing biological samples. MFS' core technology is used for airborne pathogen detection, rapid clinical diagnostics and sample preparation applications.
PositiveID's microfluidic technology alleviates all existing problems by replacing robotics with integrated microfluidics, reducing cost and increasing reliability. Its microfluidic technology also automates and increases the effectiveness of key sample processing steps used today on the laboratory bench-top, into a closed, automated system. The embedded devices perform cell lysis (including difficult spores) in less than one minute at low power, nucleic acid purification along with inhibitor removal and pre-concentration of the nucleic acids up to factors of 1000X within minutes. These processes all occur autonomously within a fully contained disposable microfluidic cartridge.
