WILMINGTON, MA--(Marketwire - Oct 26, 2012) - Implant Sciences Corporation ( OTCQB : IMSC ), a high technology supplier of systems and sensors for homeland security and defense markets, is pleased to provide the following update regarding the air cargo screening qualification testing process for its QS-B220 explosives and narcotics trace detector by the Transportation Security Laboratory ("TSL"), the testing body of the Transportation Security Administration ("TSA").

Mr. Glenn Bolduc, President and CEO of Implant Sciences, stated, "As of today, the QS-B220 is with the TSL as part of the independent testing and evaluation process. Independent testing began in early October, after we were notified that we had successfully completed certification readiness. The qualification testing is, by design, an extensive and rigorous process that requires several weeks to complete. We continue to enjoy a strong working relationship with TSL, and have every reason to believe that we will successfully achieve qualification for our QS-B220 trace detector in the near term."
