“Think small” was Walter C. McCrone’s sly motto. Sly, because he was a giant in a very small world. His world was chemical microscopy, which uses microscopical methods to solve problems, such as ...

Microscopes are of three basic types: optical, electron (or ion), and scanning probe. The modern optical or light microscope was developed in the mid-19th century. Optical microscopes use transparent ...

Engineers have developed a technology that turns a conventional light microscope into what's called a super-resolution microscope. It improves the microscope's resolution (from 200 nm to 40 nm) so ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. The new microscope uses a 405 nm laser—the same wavelength ...

With a new microscope that's as light as a penny, researchers can now observe broad swaths of the brain in action as mice move about and interact with their environments. As a mouse explores its ...

Optical microscopes have for a long time played a vital role in biomedical research. Their ability to provide multidimensional structural and functional information about a specimen in a non-invasive ...

Electrical engineers at the University of California San Diego developed a technology that improves the resolution of an ordinary light microscope so that it can be used to directly observe finer ...
