Powder microscopy is evaluation/quality control method, used for medicinal plants to study the specific microscopic characters using different staining reagent. Applications in detection of adulterants in sample by performing comparison study using authenticated sample.
What else can I help you with?
What concept of microscopy deals with the ability of the specimen to stand out against its background?
Contrast in microscopy refers to the ability of the specimen to be distinguished from its background. Techniques such as staining, phase contrast, and differential interference contrast (DIC) microscopy can enhance contrast in microscopy.
What does the word phase mean in microscopy?
In microscopy, the term "phase" typically refers to phase contrast microscopy, a technique that enhances the contrast of transparent or low-contrast biological specimens by exploiting differences in refractive index within the specimen. Phase contrast microscopy allows for visualization of cell structures and organelles that would otherwise be difficult to see with traditional brightfield microscopy.
What does FESEM mean in electron microscopy?
FESEM stands for Field Emission Scanning Electron Microscopy. It is a high-resolution imaging technique in electron microscopy that uses a field emission electron source to produce a fine electron beam for imaging the surface of a specimen at nanoscale resolution.
Which type of microscopy is used for colorless specimens?
Phase contrast microscopy is often used for viewing colorless specimens, as it enhances the contrast between different parts of the specimen based on density differences. This type of microscopy is particularly useful for observing live biological samples without the need for staining.
What is the difference between phase-contrast microscopy and bright-field microscopy?
Phase-contrast microscopy is the observation of internal structures of living microbes where as bright field microscopy is the observation of killed stained specimens and naturally colored live ones.
Introduction in basic techniques in microscopy?
Introduction to basic techniques in microscopy involves light microscopy, laser scanning, types of dyes, the cell, electron microscopy, differential interface microscopy, histological stains and histochemical stains.
Does light microscopy offer better magnification than electron microscopy?
No
When was Microscopy Society of America created?
Microscopy Society of America was created in 1942.
At what total magnification should you begin to look at a sample?
Depending on what microscopy you are doing.. Bacterial microscopy starts with 40x and Blood smear microscopy at 10x.

What are the differences between two-photon microscopy and confocal microscopy in terms of their imaging capabilities and applications?
Two-photon microscopy and confocal microscopy are both advanced imaging techniques used in biological research. Two-photon microscopy allows for deeper imaging into tissues compared to confocal microscopy, making it ideal for studying thick samples. Additionally, two-photon microscopy is less damaging to living samples due to its longer wavelength light. On the other hand, confocal microscopy provides higher resolution images and is better suited for imaging thin samples. Confocal microscopy is commonly used for studying cell structures and dynamics at a cellular level. In summary, two-photon microscopy is better for deep tissue imaging, while confocal microscopy is preferred for high-resolution imaging of thin samples.

What is dark field?
Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.
