Calibration is the process of adjusting and verifying that an instrument, for example, an optical microscope, is taking measurements accurately by comparing them to a known measurement standard or ...

It’s a problem that few of us will ever face, but if you ever have to calibrate your scanning electron microscope, you’ll need a resolution target with a high contrast under an electron beam. This ...

Nanotechnology researchers have shown that they can use a red blood cell to calibrate a sensitive instrument, an atomic force microscope. An atomic force microscope uses a tiny lever that runs over ...

Nanotechnology researchers at UC Davis have shown that they can use a red blood cell to calibrate a sensitive instrument, an atomic force microscope. "It turns around the rules of nanotechnology, by ...

(Nanowerk News) As the sizes of computer chips in electronic devices continue to shrink, traditional measurement tools (e.g., microscopes utilizing visible light) are no longer capable of examining ...
