中文摘要：智能手机生物传感器是读出液体比色测定结果的高性价比的便携式仪器。但是，当前报道的智能手机比色阅读器依赖照相机捕获后，用软件程序分析的液体检测照片。这种方法得到的结果准确性和通用性相对较低。本研究报道了一种新型智能手机比色阅读器，结合了环境光传感器和3D打印附件，读出液体比色测定的结果。研究表明，该智能手机比色阅读器能为临床诊断、环境污染及食品检测相关的液体比色测定提供可扩展、经济而准确的结果。
外文摘要：Smartphone biosensors could be cost-effective, portable instruments to be used for the readout of liquid colorimetric assays. However, current reported smartphone colorimetric readers have relied on photos of liquid assays captured using a camera, and then analyzed using software programs. This approach results in a relatively low accuracy and low generality. In this work, we reported a novel smartphone colorimetric reader that has been integrated with an ambient light sensor and a 3D printed attachment for the readout of liquid colorimetric assays. The portable and low-cost ($0.15) reader utilized a simplified electronic and light path design. Furthermore, our reported smartphone colorimetric reader can be compatible with different smartphones. As a proof of principle, the utility of this device was demonstrated using it in conjunction with an enzyme-linked immunosorbent assay to detect zearalenone. Results were consistent with those obtained using a professional microplate reader. The developed smartphone colorimetric reader was capable of providing scalable, cost-effective, and accurate results for liquid colorimetric assays that related to clinical diagnoses, environment pollution, and food testing.
