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 Spotlight) The drawbacks of existing measures for calibrating scanning probe microscopes (SPMs) based on various diffraction gratings and periodic ...

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 ...

The application of optical traps has come to the fore in the last three decades. They provide a powerful, sterile and noninvasive tool for the manipulation of cells, single biological macromolecules, ...

Current calibration methods rely on artificially constructed DNA structures or specific cellular features, each with significant drawbacks. DNA-based rulers require complex chemical synthesis and only ...

Technique allows better imaging of microdroplets; method being used to analyze plastic nanoparticles and in virus assaying. Microscopy of microdroplet volume and nanoplastic concentration. Measuring ...

New work enables optical microscopes to measure these nanometer-scale details with a new level of accuracy. Over the last two decades, scientists have discovered that the optical microscope can be ...
