健康状况和饮用水质量的诊断是联合国最重要的可持续发展目标之一。然而，在某些地区，战争和不稳定使数百万人居住在难民营和危险地区，这些地区缺乏基础设施，对水质和医疗状况的快速诊断至关重要。在这项工作中，以廉价和便携的方式开发了微流控检测芯片和光度装置来检测水中的硝酸盐浓度。所执行的测试设计为按照Griess程序工作。此外，为了使其在资源设置较少的地区简单和可用，分别使用商用的Arduino Mega和液晶显示(LCD)屏蔽来处理和显示结果。为了评估的目的，使用开发的装置测试了不同本地产品的自来水、瓶装饮用水和经家庭过滤处理的水样。测定标准溶液的吸光度与浓度的关系，得到标准曲线，决定系数(R2)为0.98。总之，这是迈向紧凑、便携和可靠的水中硝酸盐检测系统的第一步，用于医疗保健应用。
The diagnostics of health status and the quality of drinking water are among the most important United Nations sustainable development goals. However, in certain areas, wars and instability have left millions of people setting in refugee camps and dangerous regions where infrastructures are lacking and rapid diagnostics of water quality and medical status are critical. In this work, microfluidic testing chips and photometric setups are developed in cheap and portable way to detect nitrate concentrations in water. The performed test is designed to work according to the Griess procedure. Moreover, to make it simple and usable in areas of low resource settings, commercially available Arduino mega and liquid crystal display (LCD) shield are utilized to process and display results, respectively. For evaluation purposes, different local products of tap water, bottled drinking water, and home-filter treated water samples were tested using the developed setup. A calibration curve with coefficient of determination (R2) of 0.98 was obtained when absorbance of the prepared standard solutions was measured as a function of the concentrations. In conclusion, this is the first step towards a compact, portable, and reliable system for nitrate detection in water for point-of-care applications.
