Several different fluorescent labels were used to generate fluorescence images and were varied between training examples; the checkerboard images indicate fluorescent labels that were not acquired for a given example. Light Sheet Fluorescence Microscopy - an overview | ScienceDirect Topics Applications of single-molecule fluorescence microscopy. (A) The photophysical properties of a fluorophore contain information about its position and its state. This allows, for example, tracking molecules, observing conformational and constitutional changes, or following chemical reactions. (B) Examples for applications in biology and chemistry. Label-free prediction of three-dimensional fluorescence images from ... Label-free prediction of three-dimensional fluorescence images from transmitted-light microscopy Understanding cells as integrated systems is central to modern biology. Although fluorescence microscopy can resolve subcellular structure in living cells, it is expensive, is slow, and can damage cells.
