1.   Currently, scientists must use a microscope to make each pill in order to see its tiny circuitry.

2.   Such tiny circuitry is used in the smallest, fastest and most powerful computer chips in world.

3.   The recent quantum physics paper may give chip makers a way to adapt their current factories to generate tiny wavelengths of light that can generate very tiny circuitry.

4.   Tiny circuitry and digital technology, which have revolutionized the video and music industries, are being developed for hearing aids.
