👉 A phone doscope is a type of optical instrument used to study the structure and arrangement of biological cells, particularly in cell cultures. It consists of a light source (typically a laser) that directs light into the cell, causing it to emit light waves that bounce off the cell walls and then reflect back at the light source. The reflection of these waves can be used to image the internal structures of the cell, as well as the distribution of molecules within the cell. A phone doscope is typically
