What is Fluorescence Microscopy? A fluorescence microscope is an optical microscope that employs fluorescence for examining specific properties of select organic and inorganic substances. A fluorescence microscope functions by observing labeled samples; the labels here are the specific fluorescent molecules (or clusters of molecules)—termed fluorophores—that emit light when stimulated at specific frequencies. Components of a … Read more
What is Semiconductor Sequencing? Semiconductor sequencing is the integration of microchip technology with DNA sequencing where electrical signals replace the detection of light. This sequencing method is unique because it uses complementary metal-oxide semiconductor chips associated with sequencing by synthesis chemistry; so, in this respect, it opens up opportunities to make DNA analysis quicker and … Read more
What is Thyroid Gland? Definition of Thyroid Gland The thyroid gland is a butterfly-shaped endocrine organ located in the anterior neck that produces hormones such as thyroxine (T4), triiodothyronine (T3), and calcitonin, which regulate metabolism, growth, and calcium homeostasis. It plays a crucial role in maintaining the body’s metabolic rate and overall hormonal balance. Anatomical … Read more
What is cryo-EM? Principle of cryo EM Types of cryo EM Cryo-electron microscopy (cryo-EM) is a collection of special methods. These are broadly categorized into two types, mainly cryo-transmission electron microscopy (cryo-TEM) and cryo-scanning electron microscopy (cryo-SEM). Each has its own advantage in the analysis of biological samples in their native state, frozen by cryo-preparation. … Read more
What is Baran Pipette Column? Principle of Baran Pipette Column Principles of adsorption chromatography are used in the Baran pipette column. In this technique, the separation of compounds is achieved through their differential interactions with two key phases: in the stationary phase and the mobile phase. The pasteur pipette is packed with a stationary phase, … Read more
What is an autoclave? An autoclave is a device which finds applications in numerous scientific and medical institutions. Its work principle lies in using the pressure of steam for the cleansing of equipment and materials. During the autoclaving process, the following kinds of germs are killed: bacteria, viruses, and spores. The basic idea of autoclave … Read more
What is gas chromatography? Gas chromatography (GC) is a sophisticated technique that separates, identifies, and quantifies chemical components in complex mixtures. It operates on the principle of distributing the components between a mobile phase and a stationary phase. In GC, the mobile phase is an inert gas like helium, and it acts as a carrier … Read more
What is Fish migration? Fish migration is the active, regular movement of fish populations from one place to another, often over long distances and various environments. This behavior is critical to the survival of fish and is a function of varied ecological, environmental, and biological factors. Fish migration is specific to different fish species, ranging … Read more
A game changer for the microscopic world is epi-fluorescence microscopy. Imagine being able to see cells as vibrant, dynamic creatures showing off their inner workings instead of just as static objects. This method, based on the principle of fluorescence, has opened up the hidden details of life at the cellular level and made the invisible … Read more
What is Flame Photometer? Principle of Flame photometer The flame photometer is based on the principle that alkali and alkaline earth metal atoms are excited in the flame and that the light emitted when the excited atoms revert to the ground state can be measured. When you introduce a sample containing metal compounds into a … Read more
