Mediscience Technology Corp. is engaged in the design and development of medical diagnostic instruments that detect cancer in vivo in humans by using light to excite the molecules contained in tissue and measuring the differences in the resulting natural fluorescence between cancerous and normal tissue. Mediscience possesses the foundations for Optical Biopsy by developing technology based on ultraviolet (UV)-visible fluorescence, excitation, Raman, time-resolved, diffuse reflectance and Stokes shift spectroscopies. The Company is developing three products in the areas of cervical, full spectrum gastrointestinal (GI) and oral that employ its technology for cancer screening and diagnosis, and are based upon its Cancer Detection (CD) Scan, CD Ratiometer and CD Map. These devices use lamplight to provide a broad spectrum of scanning excitation light wavelengths to insure that the appropriate target tissue molecules are sufficiently fluoresced to provide maximum diagnostic sensitivity.
