  Microscopy - Wikipedia, the free encyclopedia
Microscopy is any technique for producing visible images of structures or details too small to otherwise be seen by the human eye, using a microscope or other magnification tool.
In classical light microscopy, this involves passing light transmitted through or reflected from the subject through a series of lenses, to be detected directly by the eye, imaged on a photographic plate or captured digitally.
Microscopy usually involves the diffraction, reflection, or refraction of radiation incident upon the subject of study.

As a biology student at a liberal arts institution, you’ll be challenged to think for yourself and to articulate your ideas clearly.
These courses will take you from the molecular level of biology through the ecosystem level, introducing you to the broad scope of biology, as well as the different backgrounds and areas of expertise of the biology faculty members.
Upper-level courses focus on cells and molecules, which includes cell biology, electron microscopy, molecular genetics, and microbiology; populations, which examines the structure and diversity of animals and plants, their adaptation, evolutionary relationships, behavior and ecology; and organisms, which covers cell and plant physiology and vertebrate physiology.

The Department of Cell Biology has a long tradition of excellence and innovation in the field of imaging, and electron microscopy in particular.
The ascent of Molecular Biology has not caused de demise of electron microscopy that some had predicted, but on the contrary has resulted in a renewed interest for morphological approaches as the many gene products identified through genetic screens have to be characterized in terms of function and subcellular localization.
One of the major technological approaches that we focus on in the Electron Microscopy Laboratory is that of immuno-gold labeling on ultrathin cryosections.

 SPM (AFM, LFM...) in Biology - Introduction
In biology Atomic Force Microscopy has been used traditionally to measure topography [22, 357, 721, 905, 959, 1045, 1068, 1574, 1575, 1584] and nanomechanical properties of biological samples, such as elasticity [256, 327, 360, 593, 676, 992, 995, 1569, 1736].
The variety of objects investigated using Atomic Force Microscopy in biology spans smallest biomolecules encompassing proteins, lipids, DNA, RNA and other nucleic acids, as well as rather "big" human's platelets, viruses and living cells.
The main advantage of AFM in biology as compared with other methods is that it usually doesn't require specific sample preparation and allow measuring in most physiological conditions the most of biological objects are susceptible to.

 Biology 750: Electron Microscopy
This is similar to absorption contrast in light microscopy although virtually no electrons are actually absorbed by the thin specimens used in transmission electron microscopy.
In light microscopy this would be accomplished with an annular phase plate in the diffraction plane of the objective lens; this is not very practical in electron microscopy.
This is certainly the most efficient geometry for darkfield electron microscopy since the annular detector can be designed to collect virtually all of the elastically scattered electrons and can also exclude almost all inelastically scattered electrons which degrade CTEM images by increasing chromatic aberration.
