A mobile phone can now detect whether leftovers in your fridge are safe to eat or should be discarded, the Daily Mail reported.

Researchers at the University of California, Los Angeles, have developed a device that attaches to mobile handsets that can detect small amounts of E. coli in liquid samples.

The device consists of glass capillary tubes with LED lights on either end. It is able to selectively detect low concentrations of E. coli, bacteria which can cause severe food borne disease, in water samples and milk.

The findings have been published in the Royal Society of Chemistry journal Analyst.

剩飯該不該吃？問手機(jī)

???????據(jù)英國《每日郵報》報道，冰箱里的剩飯該繼續(xù)吃，還是扔掉，手機(jī)一測便知。

???????美國加州大學(xué)洛杉磯分校的研究人員研制出一種設(shè)備，與手機(jī)連接后，能在液態(tài)樣本中檢測出微量大腸桿菌是否存在。

???????它由兩端裝有LED燈的玻璃細(xì)管組成，如果牛奶及液態(tài)樣本中具有少量大腸桿菌，便會作出反應(yīng)。大腸桿菌一些菌株食用后，可能引發(fā)嚴(yán)重疾病。

???????這一發(fā)現(xiàn)已發(fā)表在英國皇家化學(xué)協(xié)會的雜志《分析學(xué)家》上。
