Apart from being able to scrape at stains with extremely hard microscopic filaments, with a few quick runs of the eraser, the stain has already started to come away. That's aided by the fact that the dirt is pulled into the open spaces between the spindly skeletal strands and bound there...
Fluorescence microscopes are very widely used because they have greater contrast and sensitivity than ordinary scopes, and they help pick out the unique, functional bits and pieces in microscopic samples that make it easier to identify things (technically, this is called greater "specificity"). Artwo...
If a hardening mounting medium is used, which is often the case, the sample is allowed to cure overnight, so microscopic examination is possible on the following day. Permanent preparations produced in this way can be practically unlimitedly stored in the dark at room temperature or 4 °C, ...

The simplest way to count bacteria is called the direct microscopic cell count, which involves transferring a known volume of a culture to a calibrated slide and counting the cells under a light microscope. The calibrated slide is called a Petroff-Hausser chamber (Figure 7) and is similar to ...
The nano-CaCO3 suspended in kerosene is referred to as kerosene suspension of nano-CaCO3 (KSNC). The rheological beha- viors and the microscopic structure of suspensions have been inves- tigated to explain the mechanisms in which the secondary fluid and nanoparticles influence the rheology of ...
"Mould may look like fuzz, or discolouration or a stain on material like wood," ACT Health explains. "Spores are the microscopic ‘seeds’ which fungi, including moulds, release into the environment. They are sufficiently small that they can be suspended in air and widely distributed." ...
The local death investigator asked around, but after several questions and few answers, he decided to have each villager bring out his sickle and lay it out across the ground. Eventually, flies swarmed over one sickle, most likely because its owner failed to wash away microscopic tissue from ...
The Asian citrus psyllid (ACP), Diaphorina citri, is a harmful pest of citrus trees that transmits Candidatus Liberibacter spp. which causes Huanglongbing (HLB) (citrus greening disease); this is considered to be the most serious bacterial disease of cit
Light microscopes can magnify objects up to 1,000 times, revealing microscopic details. Light-microscopy technology has evolved far beyond the first microscopes of Robert Hooke and Antoni van Leeuwenhoek. Special techniques and optics have been developed to reveal the structures and biochemistry of ...
