PositiveID has declared that it has achieved a significant landmark in developing its GlucoChip, a RFID microchip that senses glucose levels. The company has built reverse anchor and anchor building blocks and also competitor constructs that are capable of attaching with glucose for producing direct and repeatable interpretation of glucose levels.
Both the building blocks and the competitor constructs can be incorporated in the glucose sensor. The company is looking forward to improve the glucose sensing system by the middle of 2011, and will shortly include the sensing system with the RFID microchip electronics to finalize the development of the glucose sensor.
Currently, the company is in the second phase of GlucoChip development. The Phase II is focused on enhancing the sensing system for its response to glucose and showing the incorporation of the parts into a steady and repeatable glucose sensing system, which will be glucose sensor’s critical component. The company monitored the binding of anchor and reverse anchor constructs with glucose and also the aptness for immobilizing on a rigid surface. The outcomes of the testing will enable the selection of ideal glucose binding pairs that can be included in the archetype.
The President and Chief Science Officer at Receptors, PositiveID's Development Partner, Robert E. Carlson stated that the accomplishment has given them more confidence for developing a reliable and repeatable glucose sensing system. He added that building a material that can attach to glucose and develop a constant response curve, which can be interpreted and compared to glucose levels, was a major task for them.
The Chairman and CEO of PositiveID, Scott R. Silverman mentioned that they are determined to take the GlucoChip to the next development phase by using their proficiency with implantable RFID microchips.
PositiveID is working with Receptors to develop the GlucoChip. The glucose-sensing microchip is developed based on VeriChip, Positive ID’s FDA certified microchip used for patient recognition and is also based on the Embedded Bio-Sensor System with Positive ID’s Patent No. 7,125,382. The Embedded Bio-Sensor System uses radio frequency recognition technology and features a remote transponder that can wirelessly interact with an implantable on-chip transponder.
