A NEW method of providing dyes for some of the commoner staining procedures has been developed and tested. A small volume of the required dye solution is prepared according to the appropriate ...

So the microscope was able to slide over the surface of individual bacteria to detect protein molecules on the cell surface and in contact with the metal.

When placed in an observation chamber within a microscope slide, the microbes swam either up or down until they collided with the glass.

Ten minutes later, you have a device that weighs 9 grams, fits in a pocket, holds regular microscope slides, and can magnify their contents more than 2,000 times using a small built-in lens.

Up to now, if scientists wanted to study blood cells, algae, or bacteria under the microscope, they had to mount these cells on a substrate such as a glass slide. Physicists have now developed a ...

Then, slides were prepared by placing a drop of blood on a glass slide and stained with dye to make the bacterial cell structures more visible.
