Hardware design and research of a portable system for MPO detection
摘要
Abstract
Objective:Myeloperoxidase (MPO) is an important sort of heme peroxidase. It can be used to identify those patients who will suffer cardiovascular diseases at higher risk in the future. In this paper, we develop a portable system for the determination of MPO by using several electrochemical principles, such cyclic voltammetry, which could gain specific current responses under specific voltages. Methods:A 16-bit, ultra-low-power MCU is utilized in our system to achieve system controlling, the hardware consists of three-electrode detection module, differential amplification module, programmable amplification module and voltage-uplift module. Results:The software is designed to sample the output of hardware, and then processes the data to calculate the concentration of MPO by specific algorithms;the result will be displayed on the LCD screen. Conclusion:The portable system can be used to detect the concentration of MPO in the buffer and in human serum. Thus, the system can be used as a portable platform for MPO detection.关键词
