$PSID In order to take advantage of such strong industry growth, biosensor companies will need to develop unique and scalable technologies that will set them apart from their competitors and set higher barriers to entry for potential competitors in the industry. This is exactly what PositiveID Corp. has been working on. They have recently completed the design of the second-phase prototype of their Firefly Dx product, which is a real-time, mobile polymerase chain reaction (PCR) pathogen detection system. This technology is expected to be completed during the first half of 2015. In even better news, the company recently reported its first revenues since the business launched, showing that the company is gaining a foothold in the industry and has overcome many of the initial start up hurdles faced by biosensor companies. Having gained entry into this blooming market early is a great step for the company, as they will be positioned to reap the rewards from the major industry-wide growth in the near future.
