WebMay 15, 2004 · A sensitive and specific optical immunoassay (OIA) has been developed for snake venom detection. The assay is based on the principle of detection of physical changes in thickness of molecular thin film resulting from specific binding events on an optical silicon chip (SILAS™-I, ThermoBioStar, Colorado, USA). Surround optical-fiber immunoassay (SOFIA) is an ultrasensitive, in vitro diagnostic platform incorporating a surround optical-fiber assembly that captures fluorescence emissions from an entire sample. The technology's defining characteristics are its extremely high limit of detection, sensitivity, and dynamic range. SOFIA's sensitivity is measured at the attogram level (10 g), ma… can a cat scan show bladder cancer
