Today’s nanoscale technologies are sophisticated
enough to be applied in an endless number of useful devices, from
sensors in touch screen devices and household appliances to
wearable biosensors that can monitor chemical levels in our blood,
muscle movement, breathing and pulse rate. In addition, there are
technologies for precision devices such as high-resolution scanning
probe microscopes which enable one to visualize surfaces not only
at the atomic level, but even the individual atoms
themselves.
