PositiveID Corporation Successfully Completes Development of Its Continuous Glucose Sensor to Accurately Measure Glucose Levels in Human Blood

Lab Tests Prove the Effectiveness of the Glucose Sensing System, a Critical Component of the Company's GlucoChip Glucose-Sensing Microchip to Measure Glucose Levels in Individuals With Diabetes


DELRAY BEACH, Fla., July 14, 2011 (GLOBE NEWSWIRE) -- PositiveID Corporation ("PositiveID" or "Company") (Nasdaq:PSID), a developer of medical technologies for diabetes management, clinical diagnostics and bio-threat detection, announced today it has successfully created and laboratory-tested a stable and reproducible closed-cycle, continuous glucose sensing system that functions in the human blood fractions that are relevant to glucose analysis in the human body. PositiveID's development of the glucose sensor, which is based on RECEPTORS LLC's ("Receptors") proprietary chemistry platform, is a critical component of the Company's implantable RFID glucose-sensing microchip, GlucoChip™, which will accurately measure glucose levels in individuals with diabetes.

PositiveID and Receptors created the glucose sensing system based on the integration of specifically designed synthetic materials. The components of the self-contained, closed-cycle sensing system were designed to interact competitively with changing physiological blood glucose levels, generating a reproducible, measurable response. The sensing system components are based on simple molecular chemistry materials, rather than biochemical reagents like enzymes or antibodies, which are unstable and can require the continuous addition of external reagents. The Company believes the measurement of glucose levels through this system will allow individuals with diabetes to monitor glucose levels in a less invasive manner than any of the systems available today.

As the Company finalizes the optimization of the glucose-sensing system, it will incorporate the glucose-sensing system with a micro-electromechanical system signal transduction unit and the electronics of its RFID microchip to complete development of GlucoChip.

Scott R. Silverman, Chairman and CEO of PositiveID, said, "We are very proud to say that we, in conjunction with the skilled team of scientists at Receptors, have completed our goal of developing a stable and reproducible glucose-sensing system. By overcoming this significant hurdle in the development of GlucoChip and accomplishing this pivotal goal, the Company will begin to look for major partners to accelerate the remaining development of GlucoChip, a project that has the potential to revolutionize the way people with diabetes monitor their glucose levels."

GlucoChip is based on the Company's FDA cleared microchip for patient identification, the VeriChip, and the Company's Patent No. 7,125,382 for an "Embedded Bio-Sensor System." The Company's Embedded Bio-Sensor System patent covers a bio-sensor system that utilizes radio frequency identification technology and includes a remote transponder in wireless communication with an implantable passively-powered on-chip transponder.

More than 25 million children and adults in the U.S. have diabetes, or over 8 percent of the population, according to the 2011 National Diabetes Fact Sheet, and the total cost of diagnosed diabetes in the U.S. was estimated at $174 billion in 2007. Worldwide, the number of adults with diabetes has doubled over the last three decades to nearly 350 million and increased nearly three-fold in the U.S., according to a study published in the British journal Lancet.
