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 ...

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 ...

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 ...

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 ...

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 ...
