Definition: Kelvin Probe Force Microscopy (KPFM), also known as Surface Potential Microscopy, is a cutting-edge scanning probe microscopy technique that measures the surface potential of materials at ...

Microscopes are valuable tools used in biological research. Traditionally scientists have used electron microscopes to clearly see subcellular structures or light microscopes to observe whole living ...

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 ...

This illustration represents a bacteria being illuminated with mid-infrared in the top left, while visible light from a microscope underneath is used to help capture the image. A team at the ...
