Microscopy is a scientific technique that involves using a microscope to examine objects that are too small to be seen with the naked eye. It allows researchers to observe and study structures, surfaces, and processes at the cellular and molecular level. There are various types of microscopes available, including optical microscopes, electron microscopes, and scanning probe microscopes, each offering different levels of magnification and resolution. Microscopy is widely used in fields such as biology, medicine, materials science, and nanotechnology, and has revolutionized our understanding of the microscopic world.
