基于Android移动终端的双通道磁弹性免疫传感装置
A Dual-Channel Magnetoelastic Immunosensing Device Based on Android Mobile Terminal
摘要
Abstract
Traditional detection instruments are unwieldy and expensive,which raises the operating threshold and greatly limits the usage scenarios and suitable users of microelectromechanical Systems(MEMS).Magnetoelastic sensor is just one of many MEMS devices fa-cing this problem needing urgent resolution.To address this issue,a dual-channel magnetoelastic immunosensing device is developed based on the Android mobile terminal,in combination with the Android framework and the hardware system(STM32F407 as the main control chip).The same parameter magnetoelastic sensor,made of Metglas alloy 2826,is used for D-dimer analysis.The experimental results demonstrate that the portable device can achieve comparable results to the vector network analyzer 3656A,a traditional instru-ment.The device can detect D-dimer concentrations in the range from 0.25 μg/mL to 2.5 μg/mL,with a detection limit of 45 ng/mL.In conclusion,the device developed possesses the advantages of being low-cost,low power consumption,portable,user-friendly,and has the potential to develop into a new generation of home-based health detection devices.关键词
