Are you allergic to peanuts and worried there might be some
in that cookie? Now you can find out using a rather unlikely source: your cell
phone.
A team of researchers from the UCLA Henry Samueli School of
Engineering and Applied Science has developed a lightweight device called the
iTube, which attaches to a common cell phone to detect allergens in food
samples. The iTube attachment uses the cell phone's built-in camera, along with
an accompanying smart-phone application that runs a test with the same high
level of sensitivity a laboratory would.
