AUSTIN, Texas, Dec. 7, 2011 (GLOBE NEWSWIRE) -- Applied Nanotech Holdings, Inc. (OTCBB:APNT) is pleased to announce that it has been awarded European Patent EP1976431B1, for its EZKnowz™, a multiple-gas breath sensor for use in medical applications for the detection of potential disease states. This patent covers the complete EZKnowz™ sensor platform, including a sample collector, analysis device and data storage device.

The EZKnowz™ sensor platform, developed by Applied Nanotech, combines existing differential ion mobility spectrometry technology with Applied Nanotech's proprietary non-radioactive ion source. The EZKnowz™ sensor platform is capable of sensing a broad range of gas species and selecting specific gasses in a complex environment. The levels of detection of the EZKnowz™ sensor platform for many gasses are on the range of parts per billion (one or more molecules in a concentration of one billion other gas molecules) and in some cases, in the range of parts per trillion, sufficient for many applications.

Unlike other breath detection systems on the market that are limited to centralized laboratories or facilities because of their size, EZKnowz™ is a compact, portable system that can be used in a variety of settings, including laboratories, doctor's offices and home-health environments.  EZKnowz™ has the potential to detect a variety gases and diseases, including Mercaptan/BTEX, lung cancer detection, influenza detection, pharmaceutical contamination, wound healing/infection detection and plant disease detection. In addition, EZKnowz™ has been shown to identify body odor biometrics for use in military and homeland security applications, including the detection of explosives.

Applied Nanotech is also pleased to announce that it has hired Dr. Royce Johnson to accelerate its business development initiatives in medical sectors. Dr. Johnson spent 14 years with therapeutic medical device developer, Kinetic Concepts, Inc. (KCI), where he was instrumental in developing and commercializing breakthrough developments revolutionizing wound therapy, tissue engineering, skin grafting, phototherapy, and therapeutic hypothermia. Dr. Johnson was twice recognized by Frost & Sullivan as their Most Valuable Thought Leader in MindXchange Programs. He earned his bachelor's, master's, and doctoral degrees in biology and bioengineering at the University of Utah and holds a certificate in strategy and innovation from MIT Sloan School of Management.
