Sample Preparation Techniques in Light Microscopy | Microbiology

One of the most attractive features of light microscopy is the ease with which most specimens can be prepared for examination. Preparation often involves nothing more than mounting a small piece of the specimen in a suitable liquid on a glass slide and covering it with a glass coverslip. The slide is then positioned on the specimen stage of the [...]

Centrifugation and Subcellular Fractionation of Microscopic Components

Centrifugation is a useful means of isolating and purifying cellular components because most organelles and macromolecules differ from one another significantly in size and density (and sometimes also in shape, especially in the case of macromolecules). These properties, as well as the density and viscosity of the surrounding medium, determine the rate at which a specific particle will move when [...]

Design of Atomic Force Microscope (With Diagram)

In this article we will discuss about the design of atomic force microscope, explained with the help of a diagram. An atomic force microscope instead of using a lens is provided with a probe to examine the surface of a specimen with a sharp tip which may be several micrometers in and less than 10 nm in diameter at the [...]
