About Isonics Corporation

        Isonics Corporation has three business divisions: (1) Isonics Semiconductor, (2) Isonics Life Sciences, and (3) Homeland Security and Defense. Isonics is a world leader in isotopically engineered materials and through its semiconductor division produces isotopically pure silicon-28 chemicals and wafers for the semiconductor industry. Through advances in nanotechnology, the Company is also focused on research and development opportunities for further, value-added product and application development. Isonics' Life Sciences division markets and sells stable isotopes for the health care industry such as carbon-13 for diagnostic breath tests and drug design, and radioisotopes and stable isotopes, such as oxygen-18 for positron emission tomography (PET) imaging. Stable isotopes can be thought of as ultra pure materials. This high degree of purification provides enhanced properties as compared to natural materials.
