Reports from University of Mazandaran Advance Knowledge in Chemical Sensors and Actuators (A new sol-gel optical sensor with nonporous structure for determination of trace zinc)

By a News Reporter-Staff News Editor at Journal of Technology -- Researchers detail new data in Chemical Sensors and Actuators. According to news reporting originating in Babol Sar, Iran, by VerticalNews journalists, research stated, "We report herein the development of a novel optical sensor based on incorporation of 1,5-diphenylcarbazone as a sensitive reagent into the nanopores of a transparent glass like material through the sol-gel process and suggest how it may be useful for determination of zinc in aqueous solutions. The sensors were fabricated by spin-coating onto glass substrates."

The news reporters obtained a quote from the research from the University of Mazandaran, "To survey the catalysis type effect on leaching behavior of the sensor, both acid- and base-catalyzed sol-gel processes were studied. Results indicated that acid-catalyzed method is suitable to give more stable thin films with constant sensitivity and response time for a long period of time. The fabricated sensor can be used for determination of zinc in the range of 0.03-1.2 mu g mL(-1) with a detection limit of 0.016 mu g mL(-1). It also showed reproducible results with relative standard deviation of 3.6 and 2.2% for 0.1 and 0.8 mu g mL(-1) of Zn (II), respectively, along with a fast response time of similar to 150 s. This optode is stable and could be stored for at least 2 months without observing any change in its sensitivity."

According to the news reporters, the research concluded: "The developed sensor was successfully applied to the determination of zinc in serum of diabetic patients and water sample and validated against inductively coupled plasma optical emission spectrometry method."
