Research team resolves decades-long problem in microscopy

When viewing biological samples with a microscope, the light beam is disturbed if the lens of the objective is in a different medium than the sample. For example, when looking at a watery sample with a lens surrounded by ...

Discovery of the first fractal molecule in nature

An international team of researchers led by groups from the Max Planck Institute in Marburg and the Philipps University in Marburg has stumbled upon the first regular molecular fractal in nature. They discovered a microbial ...

Advanced microscopy technique offers a new look inside cells

Imagine tuning into a football game, but all of the players are invisible except for the two quarterbacks. Without being able to see the orchestrated movements of the full teams, this would be a very confusing game to watch.

New method achieves 4D imaging of fluids in pores

A method based on CT (computed tomography)—a type of imaging that is widely used in hospitals—can help improve our understanding of CO2 storage, batteries, and processes in the body such as nutrient uptake.

Microscopy

Microscopy is the technical field of using microscopes to view samples or objects. There are three well-known branches of microscopy, optical, electron and scanning probe microscopy.

Optical and electron microscopy involve the diffraction, reflection, or refraction of electromagnetic radiation/electron beam interacting with the subject of study, and the subsequent collection of this scattered radiation in order to build up an image. This process may be carried out by wide-field irradiation of the sample (for example standard light microscopy and transmission electron microscopy) or by scanning of a fine beam over the sample (for example confocal laser scanning microscopy and scanning electron microscopy). Scanning probe microscopy involves the interaction of a scanning probe with the surface or object of interest. The development of microscopy revolutionized biology and remains an essential tool in that science, along with many others including materials science and numerous engineering disciplines.
