Abstract

The caffeine chemical sensor was developed by co-immobilizing sodium periodate (NaIO4), 3-methyl-2-benzothiazolinone hydrazone (MBTH), and acetic acid (CH3COOH) onto paper by using an adsorption technique. The addition of caffeine solution could change the color of the sensor from white to pale blue which can be then captured by using a flatbed scanner and quantified by the ImageJ program, known as a scanometric technique. Method validation such as linearity, LOD, LOQ, precision, and accuracy of the sensor was done by using caffeine standards. The result of caffeine analysis using the developed chemical sensor-scanometric method agreed with that of the spectrophotometric method, suggesting that the developed sensor with scanometric technique can be used as an alternative method for caffeine assay in coffee samples.

基于纸的化学传感器的开发,以确定咖啡样本的咖啡因水平
采用吸附法将高碘酸钠(NaIO4)、3-甲基-2-苯并噻唑啉酮腙(MBTH)和乙酸(CH3COOH)共固定在纸上,制备了咖啡因化学传感器。添加咖啡因溶液可以将传感器的颜色从白色变为淡蓝色,然后可以使用平板扫描仪捕获并通过ImageJ程序进行量化,称为扫描测量技术。采用咖啡因标准品对传感器的线性度、LOD、LOQ、精密度和准确度进行验证。所建立的化学传感器-扫描法测定咖啡中咖啡因的结果与分光光度法的结果一致,表明所建立的传感器-扫描法可作为咖啡样品中咖啡因测定的一种替代方法。
