UCLA researchers have redefined the concept of a microscope by removing the lens to create a system that is small enough to fit in the palm of a hand but powerful enough to create three-dimensional ...

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 ...

The demand for disposable miniature imaging platforms (DMIPs) is growing rapidly. Used for commercial, scientific, medical, and educational purposes, DMIPs have numerous applications but can be ...

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 ...

A new imaging technology uses polarized 'optical vortices' to provide a detailed, dynamic view of molecules in motion. Understanding the nitty gritty of how molecules interact with each other in the ...

Conventional light microscopy has been instrumental for the study of cells and microorganisms; fluorescence microscopy has enabled visualization of even smaller cell features by selectively adding ...

This article discusses how optical microscopy is used in analyzing, visualizing and imaging nanomaterials as well as its limitations and recent studies related to optical microscopy utilization in ...

In the late 17th century, a Dutch draper and self-taught scientist named Antonie van Leeuwenhoek earned renown for building some of the best microscopes available at a time when the instrument was ...
