So we clipped part of this sensor, and attached that to a switch to control the cells, and we packed this switch into an engineered virus and injected that into the brain of the mice.

By measuring the change in the dielectric constant of the surface of a sensor, thus detecting the presence of water or ice on the sensor's surface.

This protects the sensor and access a lens to precisely focus it on your finger.

Here, it is locked away from everything else accessible only by the Touch ID Sensor.

The sensor uses advanced capacitive touch to take and essence a higher resolution image of your fingerprint on the subepidermal layers of your skin.

The sensor would have to be inexpensive, rapid, simple, sensitive, selective, and minimally invasive.

One of the first working examples of a synthetic nanosensor was built by researchers at the Georgia Institute of Technology in 1999.

So, I set up scientific criteria as to what a sensor would have to look like in order to effectively diagnose pancreatic cancer.

One of the best parts of the sensor, though, is that it has close to 100 percent accuracy, and can detect the cancer in the earliest stages, when someone has close to 100 percent chance of survival.

Giving mice rapamycin, a drug that inhibits Tor, extends lifespan even if the mice are fairly old when the treatment begins.

Its sensor beams look both forward and backward at the same time, allowing it to do new exploration while it's still achieving geometric sensor lock on what it's gone through already.

And so in the next two to five years, this sensor could potentially lift the pancreatic cancer survival rates from a dismal 5.5 percent to close to 100 percent, and it would do similar for ovarian and lung cancer.
