According to IFL Science, a low-cost dongle created by researchers at Columbia Engineering can easily detect syphilis and HIV, in just 15 minutes. From the user all is required is a "finger prick of blood" and electrical power from a smartphone.

The small, lightweight device contains a lab on a chip consisting of a disposable plastic cassette containing the necessary reagents for the tests. Blood from a patient is drawn through microscopic channels where it then meets chemicals that react with HIV and syphilis antibodies to produce a color change. This can then be picked up by a set of photocells in the dongle, and the results are then sent to an app on the attached smartphone or computer.
