Founded by a core team of scientists through an Entrepreneur Leave of Absence program from US Department of Energy's Pacific Northwest National Laboratory (PNNL), XL Sci-Tech Inc is a specialty materials R&D firm capable of manufacturing precision and multi-function microspheres and nano-spheres in large quantities. Under development by the firm's personnel are new materials for use in repairing broken bones and other bone defects. Principals are also developing new therapeutic materials for cancer treatment, personnel are developing immobilizing radionuclides for therapy and diagnostics, encapsulating therapeutics, biologics, or traceable markers into micro- and nano-dimensioned carriers such as microspheres, microfibers or nano-spheres. The company holds a special radiation license for their Radioactive Materials Processing Facility under the direction of the firm's internationally respected health physicists. Products in development and in-vitro and in-vivo evaluations include radioactive microspheres/nano-spheres and radiological devices for various soft tissue tumors and targeted cancer therapies. In sum, the firm's products are Radioactive Glass Microspheres for Radiation Therapy; Bioactive Glass Microspheres, Fibers and Powders; High Silica and Alkali-Free Microspheres; and Metal or Metal Coated Microspheres.
