Left: Images of fluorescent particles that are above, at and below (top to bottom) the vertical position of best focus of a microscope. Calibrating the effects of lens aberrations on the apparent ...

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 ...

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 ...

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 ...

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 ...

Size is one of the most important physical features when identifying and characterizing an organism in the lab. The exact size of an organism can be determined using a calibrated ocular micrometer. An ...

Measurements of biomechanical properties inside living cells require minimally invasive methods. Optical tweezers are particularly attractive as a tool. It uses the momentum of light to trap and ...

(Nanowerk News) Spotting molecule-sized features—common in computer circuits and nanoscale devices—may become both easier and more accurate with a sensor developed at the National Institute of ...
