“Portable rapid and low cost aflatoxin sensor with LAMP-Electrochemical detection kit” was selected for 2015 NRCT Invention Award. This work is a collaboration between researchers from NECTEC and BIOTEC. Leading the BIOTEC team is Ms. Wansika Kiatpathomchai, Head of Bioengineering and Sensing Technology Laboratory. The kit operation is based on the measurement of current response as a result of electrochemical reaction from aflatoxin on an innovative graphene-based test stripe fabricated by printing technology. The current is then accurately converted into aflatoxin concentration and output on the built-in LCD display. The disposable graphene electrode offers high efficiency, high detection sensitivity and wide aflatoxin detection range 0-80 ppb (maximum contaminated level of aflatoxin = 20 ppb).
