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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale ...

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 ...

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 ...

There are two fundamental ways to identify isotopic labels. The most direct method is mass spectrometry, in which a material is broken down into individual atoms or molecules, given electrical charge, ...

Recent advances in fluorescence nanoscopy have pushed resolution to the 1–10 nm range, enabling the direct visualization of individual molecules even in crowded biological environments. Achieving this ...

At school, it's often presented as a tidy double helix but scientists are revealing the varied and intricate shapes of DNA molecules. DNA is a molecule found in just about every living cell. Because ...

Great things come in small packages and now scientists have an easier way to see what they look like thanks to a new microscope that creates high-resolution, 3-D images of structures measured in ...
