Phase-contrast microscopy is especially effective for viewing details of internal structures within live cells. It uses phase shifts caused by differences in refractive indices to enhance contrast and reveal organelles and other internal structures that are not visible with other types of microscopy. Transmission electron microscopy and scanning electron microscopy are both useful for viewing external structures and details at high resolution, but they require samples to be fixed and/or coated with metal, which kills the cells. Bright-field microscopy is a basic form of microscopy that does not provide enough contrast to view internal structures in live cells.
