Metaoptics is a flat optics technology that uses an array of subwavelength nanostructures to bend and steer light. A typical metalens can use an array of sub-100-nm-diameter pillars to implement the...

Optogenetics has transformed experimental neuroscience by manipulating the activity of specific cell types with light, enabling in vivo neuromodulation with millisecond temporal resolution. Visible...

The Casimir force is a quantum phenomenon that results in an attractive force between two closely spaced uncharged conductive surfaces. This force arises from the quantum vacuum fluctuations of the...

A linear positioning stage, also known as a linear stage or translation stage, is a precision mechanical device used to accurately move and position objects along a linear axis. These stages are...

Microscopy is a scientific technique that involves the use of microscopes to observe and study objects that are too small to be seen with the naked eye. Microscopes are instruments that magnify and...

Scanning electron microscopy (SEM) is an advanced imaging technique used in microscopy to obtain high-resolution, three-dimensional images of the surfaces of solid specimens. SEM achieves this by...
