　　科学美国人60秒中英文翻译：智能手机验证饮水安全

　　科学美国人60秒英文文本

　　A virtual cottage industry has emerged around finding innovative uses for smartphones,

　　well beyond basic calling, texting and Internet access.

　　In particular, there's been a lot of interest in turning iPhones into something like the Star Trek medical tricorder.

　　For example, University of Illinois researchers are developing an app and cradle-like device that makes the iPhone a biosensor. The key is the smartphone's camera and processing power combined with the lenses and filters located in the cradle.

　　Just put a sample of what you want to study on a slide and insert it into the cradle. The iPhone screen indicates a shift in wavelength when the cradle's photonic crystal detects toxins, proteins, bacteria, viruses or other biological materials on the slide. The researchers published in the journal Lab on a Chip.

　　Imagine using a smartphone to tell if there are toxins in harvested corn and soybeans or pathogens in a water supply. That's a handy tool that lowers the cost of medical fieldwork. Plus, when you're done, it's easy to call in the results.
