Micro-manipulators are precision instruments used to handle and manipulate tiny objects, often at the microscopic level. They are commonly employed in fields like biology, materials science, and nanotechnology to perform tasks such as positioning cells, moving small components, or conducting experiments on minute samples. These devices can be operated manually or controlled by computer systems, allowing for high accuracy and control. Micro-manipulators often feature fine-tipped tools that can interact with delicate structures without causing damage, making them essential for research and development in various scientific disciplines.
