Opto-electrophoretic detection of bio-molecules using conducting chalcogenide glass sensors

Yang, Zhiyong; Fah, Megan K.; Reynolds, Kelly A.; Sexton, Jonathan D.; Riley, Mark R.; Anne, Marie-Laure; Bureau, Bruno; Lucas, Pierre


Novel telluride glasses with high electrical conductivity, wide infrared transparency and good resistance to crystallization are used to design an opto-electrophoretic sensor for detection and identification of hazardous microorganisms. The sensor is based on an attenuated total reflectance element made of Ge-As-Te glass that serves as both an optical sensing zone and an electrode for driving the migration of bio-molecules within the evanescent wave of the sensor. An electric field is...[Show more]
