Calibration is the process of adjusting and verifying that an instrument, for example, an optical microscope, is taking measurements accurately by comparing them to a known measurement standard or ...

Light--and all waves--can bend around the corners of obstacles found along its path. Because of this phenomenon, called diffraction, it is impossible to focus light onto a spot that is smaller than ...

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 ...
