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

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 ...

Calibrating and characterizing the performance of fluorescence microscopy systems is an important part of imaging operations, and as the microscopy platforms have become more advanced, so calibration ...

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 ...

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 ...

Researchers at the US National Institute of Standards and Technology (NIST) and their colleagues have developed standards and calibrations for optical microscopes that allow quantum dots to be aligned ...

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 ...

Innovation brings 3D-nanometer precision to bio-imaging instrument. − Nature is three-dimensional, so it has to be studied and viewed in 3D, says Professor Edward Hæggström from the Electronics ...
