Simultaneous Determination of Heavy Metals Using Array Based Optical Chemical Sensor

Choi Y., Ryoo D., Park S.H., Park S.Y., Park S.H., Park S.Y., Jeonju University, KR

A sol-gel optical chemical sensor encapsulated with complexing agents for simultaneous detection of selected heavy metals such as chromium, lead, mercury, and iron in aqueous media was fabricated. The sensor was prepared by acid catalyzed [...]

A Fiber-Optic Biosensor Based on Monooxygenases and Sol–Gel Entrapped Fluoresceinamine for Trichloroethene and Tetrachloroethene

Ryoo D., Kim Y., Jeun K., Wood T., Choi Y., Jeonju Univ., KR

Tetrachloroethene (a.k.a. perchloroethene, PCE) and trichloroethene (TCE) are the most frequently detected groundwater contaminants which are suspected to cause cancer in humans. Monitoring of these carcinogens suffers from high costs and inaccuracy caused by cumbersome [...]
