Micro-manipulation is a technique used in various scientific fields to handle and manipulate tiny objects, often at the cellular or molecular level. This process is essential in areas like cell biology, where researchers may need to move or alter individual cells, or in nanotechnology, where precise control over nanoscale materials is required. The tools used in micro-manipulation include micromanipulators, which allow scientists to position instruments with extreme accuracy. These tools can be used for tasks such as injecting substances into cells, isolating specific cells for study, or assembling small components in microfabrication.
