Using conventional fluorescence microscopy for biological imaging can be challenging because this technique does not construct 3-D images needed for 3-D specimens, and it is not able to gaze past cell features to view what happens inside certain biological structures. Confocal microscopy uses optical sectioning to obtain multiple, thin, 2-demensional slices of a sample to construct 3-D models. This enables studying 3-D structures with fast dynamic processes, long-term time-lapses, or details inside the cell membrane, all possible with live cells.
