Microscopes have existed for over 350 years but the latest development would not be recognisable to the pioneers of studying the smallest scales. A team from Rice University in Houston, Texas, which ...

Unlike traditional microscopes, which use light, the new approach uses DNA 'bar codes' to label each molecule in the cell. From readings of the complex interactions of these labels with the molecules ...

To observe living cells through a microscope, a sample is usually squeezed onto a glass slide. It then lies there calmly and the cells are observable. The disadvantage is that this limits how the ...

Parts of a microscope and how a light microscope works Fundamentally, a microscope comprises two subsystems: an illumination system to illuminate the sample and an imaging system that produces a ...

Scientists have developed a new microscope which enables a dramatically improved view of biological cells. The researchers at the University of St Andrews have found a way to see far more detail ...

The microscope works in two basic modes - epifluorescence and reflection. In epifluorescent mode, the laser excites fluorescence within the sample - this is either natural fluorescence ...

The 2014 Nobel Prize in Chemistry has been awarded to a trio of researchers for improving the resolution of optical microscopes. Eric Betzig, Stefan Hell and William Moerner used fluorescence to ...
