Nanotechnology is a subminiature, unseen world that affects a tremendous number of things. Someday, it could even save your life.

Two devices in development locally, at the Washington Nanofabrication Facility, could end up in ambulances in the future.

The first device tells scientists whether platelets are functioning correctly and could help tell if a patient is bleeding internally on the way to the hospital.

A second device uses light to detect pathogens including bacteria or viruses. In 30 seconds to three minutes, the device can show whether there are even low concentrations.

But WNF has a problem -- the facility is maxed out. Associate Director Mike Khbeis is hoping $28 million marked for expansion and upgrades holds, because for these devices and others, there's more work ahead.
