For decades, a laboratory procedure known as transmission electron microscopy (TEM) has been used to test for asbestos in samples taken at construction sites. Researchers at the University of Warsaw's ...

Reflection contrast microscopy can image small sections of cells by suppressing stray reflections. This is necessary when imaging biological samples, because biological objects tend to have reflected ...

Brightfield microscopy has been widely used for hundreds of years, while reflection contrast microscopy is relatively new technology. As one of the earliest and simplest microscopy techniques, ...

Recent technological advances in conjunction with major developments in fluorescent markers have made fluorescence microscopy an extremely powerful tool. René Hessling and Thorsten Kues of Carl Zeiss ...

Unprecedented views of the interior of cells and other nanoscale structures are now possible thanks to innovations in expansion microscopy. The advancements could help provide future insight into ...

Until today, skin, brain, and all tissues of the human body were difficult to observe in detail with an optical microscope, since the contrast in the image was hindered by the high density of their ...

Limited by the laws of physics, scientific discoveries and the advance of knowledge can be bound up in a series of slow proceedings. In microscopy, up until the early 21 st century, the diffraction ...

In biology, seeing can lead to understanding, and researchers in Professor Edward Boyden's lab at the McGovern Institute for Brain Research are committed to bringing life into sharper focus. With a ...

Light microscopy is a key tool that scientists use to image cells, organelles, subcellular structures, and molecules such as proteins and nucleic acids. Because visible light leaves biological ...
