Engineers can detect ultra rare proteins in blood using a cellphone camera

Commercial approaches to ultrasensitive protein detection are starting to become available, but they are based on expensive optics and fluid handlers, which make them relatively bulky and expensive. Knowing that having this sort of diagnostic system available as a point-of-care device would be critical for many conditions, especially traumatic brain injury, engineers have developed a test that uses off-the-shelf components and can detect single proteins with results in a matter of minutes.
