進入中英對照讀新聞---Fingerprints prove more than just identity 指紋不只能驗明身分
U.S. scientists say they have developed technology that can detect trace amounts of explosives, drugs or many other substances through fingerprints.
美國科學家表示，他們已開發出能夠透過指紋來偵測微量爆裂物、毒品或許多其他物質的技術。
Purdue University researchers say their new technology -- desorption electrospray ionization, or DESI -- can also distinguish between overlapping fingerprints left by different individuals
普渡大學研究人員說，他們運用的「脫附電噴灑離子化」（DESI）新科技，也能夠辨識不同人所留下的重疊指紋。
Professor R. Graham Cooks, the lead researcher, says DESI can read a fingerprint’s chemical signature to determine what a person recently handled.
該研究領導人庫克斯教授說，DESI能判讀指紋的化學記號，來判定一個人最近觸摸過什麼東西。
DESI involves spraying a solvent onto a fingerprinted surface and then analyzing the droplets that scatter off the print. The technique provides a "chemical image" of the fingerprint with higher resolution than other techniques, allowing researchers to detect minute traces of compounds that were on the fingertips of the person who left the print.
DESI牽涉到將一種溶劑噴灑到沾有指紋的表面，然後分析散佈在指紋外圍的小水滴。這種技術提供比其他技術更高解析度的指紋「化學影像」，讓研究人員能夠偵測到留下指紋那個人指尖上的細微化合物蹤跡。
The image can also be analyzed with standard fingerprint imaging software to try and identify that person. On the forensics front, this technique can pick up small amounts of drugs like cocaine or THC from marijuana, as well as compounds from explosives.
這種影像也能利用標準指紋造影軟體加以分析，試著指認出那個人的身分。在鑑識科學方面，這種技術能夠蒐集到諸如古柯鹼或大麻中「四氫大麻酚」成分等少量毒品，以及來自爆裂物的化合物。
新聞辭典
distinguish ：動詞，區別；識別。例句： He can distinguish a genuine antique from a reproduction.（他能區別真正的古董與複製品。）
trace amounts of ：片語，微量的。trace在此為名詞，指「絲毫、微量」。trace elements則是「微量元素」。
minute：形容詞，微小的；詳細的。例句：A minute examination revealed fingerprints on a glass. （經詳細檢查後發現一只玻璃杯上留有指紋印。）
