美国伊利诺伊州技术学院的研究人员约瑟夫·斯特尔设计了一种可从人的呼气中即刻“嗅”出肺结核的电子鼻。相比之下,现阶段普遍采用的结核菌素皮肤试验法,需要48～72小时才能获得结果。电子鼻由连接于计算机的传感组件构成,而计算机上配备了先进的模型识别规则系统。当结核杆菌在人的肺部生长繁殖时,必然要吸取某些营养成分,并分泌出其他物质。电子鼻则可以闻出结核杆菌分泌出来的那些特殊化学物质的气味。总的说来,电子鼻与呼气 Joseph Steele, a researcher at the Illinois Institute of Technology, designed an electronic nose that instantly “sniffs” pulmonary tuberculosis out of human exhalation. In contrast, the current prevalence of tuberculin skin test method, takes 48 to 72 hours to get results. The electronic nose is made up of sensing components connected to a computer, which is equipped with an advanced system of rules for model recognition. When Mycobacterium tuberculosis in the human lung growth and reproduction, it is necessary to absorb certain nutrients, and secretion of other substances. Electronic nose can smell the smell of those special chemicals secreted by Mycobacterium tuberculosis. In general, electronic nose and exhale
