Implant Sciences Receives $338,000 Navy Contract for Advanced Portable Explosives Detector

(WAKEFIELD, Mass., Nov. 30, 2005) -- Implant Sciences Corporation(AMEX: "IMX", "IMX.WS") a developer and manufacturer of products for national security, medicine and industry, today announced the award of a $338,000 contract from the U.S. Navy to design a portable explosives detector which will integrate features of the Company's Quantum Sniffer(TM) handheld and desktop detectors into a combined handheld and backpack device. This design will provide the Navy with a more portable explosives detector which can be used in more confined areas while providing the operator/inspector increased mobility and use of hands. Delivery of this newly designed portable explosives detector is scheduled within the next eight (8) months. The proprietary Quantum Sniffer technology and products are differentiated from that of the competitors. The Company's products detect a wide array of explosives, including PETN, which is the difficult to detect active component of Semtex, using a proprietary non-contact sampling system. The equipment does not require radioactive sources or consumables, as is required by competitive products. Dr. Anthony J. Armini, PhD., CEO of Implant Sciences, commented, "The U.S. Navy and Implant Sciences have been working cooperatively over the past several years to take our Quantum Sniffer technology from a concept to a commercial product. This new contract should enable us to configure our currently available products into a new device that should meet the Navy's design requirements for explosives detection. We believe the Quantum Sniffer technology, which has been clearly differentiated from competitive technologies and products, is well suited for the applications requested by the Navy and should result in a device that provides the operator greater flexibility and efficiency in carrying out the task of inspecting vessels, vehicles and military installations for the presence of explosive materials. We are pleased with the Navy's decision to have us design equipment which specifically fits their special needs using Implant's Quantum Sniffer technology."
