Scientists have devised a 3D-printed optical microscope that can detect individual molecules and image biological samples with ultrahigh resolution 1. State-of-the-art microscopes provide impressive ...

When trying to measure molecular structures with nanometer precision, every bit of noise shows up in the data: someone walking past the microscope, tiny vibrations in the building and even the traffic ...

Optical and scanning electron microscope images of a nano-LED device that uses AC power instead of DC power, which could be a game-changer for sharper near-eye displays. Journalists may use this image ...

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...
