Objective
The overall goal of this project is to develop an easy-to-use, economical, and sensitive test apparatus that offers on-site speciation and quantification of trace levels of inorganic and organic arsenic compounds in rice and rice products. Our proposed device will provide a level of accuracy and reliability typically only available in expensive and time-consuming laboratory tests.The main objective of this project is to develop a highly accurate sensor for trace-level quantification of arsenic species including AsIII, AsV, and DMA/MMA in rice extract samples. Specifically, the sensor will be designed to detect arsenic in rice at a concentration of 0.01 mg/kg or lower.The technical objectives of the Phase I program are as follows:Objective 1. Optimize Electrochemical Detection MethodsObjective 2. Refine and Fabricate High Resolution MicroarrayObjective 3. Develop Sample Testing ProceduresObjective 4. Validate Arsenic Speciation Sensor
