Microscope

The most powerful optical microscope, such as the advanced super-resolution microscopes, can achieve resolutions down to a few nanometers, allowing researchers to visualize structures at the molecular level. These microscopes use techniques like structured illumination, stimulated emission depletion, or stochastic optical reconstruction microscopy to surpass the diffraction limit of conventional light microscopes. They enable unprecedented […]

Yes, viruses are visible under a microscope. They are too small to be seen without magnification. When viewed under a microscope, viruses appear as tiny particles with unique shapes and structures. Their size and features can vary depending on the type of virus. Scientists and researchers use powerful microscopes to study viruses and understand their

No, centrioles are not typically visible under a light microscope. Centrioles are small, cylindrical structures found in animal cells, and they play a crucial role in the organization of microtubules during cell division. However, centrioles are very small and are below the resolution limit of a light microscope, which is approximately 200 nanometers. Therefore, they

No, electron microscopes cannot generally be used to observe living cells. The preparation process for electron microscopy involves dehydration and vacuum conditions that are incompatible with maintaining living cells. Electron microscopes use electron beams instead of light to achieve much higher resolution images than light microscopes. However, the sample preparation for electron microscopy involves fixing,
