👉 Galvanoscope is a device used to visualize and study living cells, which is particularly useful in medical research. It consists of an iron oxide cell, called a galvanometer, that can be moved around by electric current through it. The cell's shape and size change as the current changes, allowing researchers to observe the movement of the cell and its components. This technique has revolutionized medical diagnostics and is now used in many fields including biotechnology, nanotechnology, and optoelectronics.
