Optical frequency comb spectroscopy: That's the mouth-full which describes a
revolutionary new method of detecting diseases by using only a person's breath! Researchers are touting it as a painless (and definitely non-invasive) technique that can easily detect various diseases using a laser to analyze the air you exhale.
Believe it or not, we breath out somewhere around a thousand chemicals. These exhalations contain very tiny amounts of chemicals which can flag diseases such as lung cancer. The whole process can pinpoint the analysis so well that even asthma can be detected!
Results come back very quickly too. All the patient has to do is breath into a tube which has a laser shining into it. Molecules are analyzed lightning fast; no blood sample, no pain. This device still has some development to go before it can be used widespread, but imagine being able to detect such ailments with a technique as easy as breathing.

通过呼吸就能检测出疾病?
光学频率搜索光谱: 通过一个人的呼吸就能检测出各种疾病，这是种具有划时代改革的新方法。研究人员吹捧它为无痛苦的，（绝对绝对不用吸收）的技术，该项技术通过使用激光分析你所呼出的气体就能很容易地把各种疾病检测出来。
不管相信与否, 我们呼出的气体周围有一千种化学物质. 这些散发物包含着很小数量的化学物质,这些物质能识别疾病, 例如肺癌。整个过程能很好的进行精确的分析，甚至连哮喘也能被检测到。
结果也能很快地得到反馈。所有的病人必须把气呼入一个激光能照入的小管子里，分子的分析进行得非常之快，无需血液样本，没有痛苦。这种设备在得到广泛应用之前还需要些改良，但是可以想象到它也能像呼吸那样地轻易地检测出各种疾病。
