Optical microscopes depend on light, of course, but they are also limited by that same light. Typically, anything under 200 nanometers just blurs together because of the wavelength of the light being ...

Microscopes have long been scientists' eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been ...

Fluorescence microscopy is a major workhorse in life sciences, biophysics, and physical chemistry, as it allows visualization with great specificity and sensitivity. In particular, the detection of ...

A method for measuring the temperature of nanometer-sized samples within a transmission electron microscope (TEM) has been developed by Professor Oh-Hoon Kwon and his research team in the Department ...

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 ...

A team has constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its low ...

Jordan A. Hachtel is at Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831, USA. There are two fundamental ways to identify isotopic labels. The most direct method is mass spectrometry, in ...

It is increasingly important for manufacturers of high tech materials and coatings to understand exactly what is going on at the surface of their products right down to the nanometre level. It has ...

An electron microscope can now distinguish, at the scale of columns of atoms, how certain electrons are distributed around ...
