A nano gadget to diagnose any disease

Now, a nano gadget to diagnose any disease
Scientists have developed a nano gadget which they claim could diagnose a number of diseases in a single liquid sample and give an instant result.

According to the scientists, if DNA from one of those pathogens is present in a sample, it will bind to the nanowire with the matching sequence, a process that changes the wire's conductivity, the New Scientist reported.
