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 ...

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 ...

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 ...

Scientists boost the accuracy of optical microscopes to image microdroplets in flight and apply the method to analyze the concentration of plastic nanoparticles. Sneezes, rain clouds, and ink jet ...

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 ...

Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical "hotspot" of a ...
