This scanning electron micrograph depicts the functional part of a nano-biosensor containing silicon nanowires. Field effect transistors are best known for their key role in computer microprocessors, but their compatibility with various microfabrication strategies has also led researchers to study them for biosensing applications. For example, glucose biosensors may lead to important innovations in the management of diabetes. The lithographic manufacturing processes involved in their production may mean that such sensors can be produced in quantity and scaled for different applications.
"Exploring Size - Scented Balloons" lets visitors use their sense of smell to explore the world on the nanoscale. They learn that we can smell some things that are too small to see, and that a nanometer is a billionth of a meter.
