近日,大连理工大学黄辉团队发明了一种“基于金属波导毛细管的便携式、低成本光度计”。其可用于超高灵敏度的光度检测,并且对微量物质的检测能力提升了3000多倍。在生命科学、食品安全和环境监测等领域,液体痕量分析是当前亟待解决的课题,而光度计(或称分光光度计)是目前检测液体中微量物质的最常用仪器之 Recently, Huang Hui, Dalian University of Technology team invented a “based on metal waveguide capillary portable, low-cost photometer ”. It can be used for ultra-high sensitivity photometric detection, and the detection of trace substances increased by 3000 times. In the fields of life sciences, food safety and environmental monitoring, liquid trace analysis is the urgent issue to be solved at present, and the photometer (or spectrophotometer) is the most commonly used instrument for detecting trace substances in liquids
