A fluorescence microscope mainly consists of an optical system including a light source, filter, dichroic mirror, and objective lens. Figure 3 shows a schematic diagram of a commonly used epifluorescence microscope. In an epifluorescence microscope fluorescence microscope, light emitted from the light source (excitation light) has its unwanted wavelengths cut off by an excitation filter. The excitation light is then reflected by a dichroic mirror and irradiated onto the sample through an objective lens. The sample irradiated by the excitation light emits fluorescence, which is passed through the objective lens, dichroic mirror, and fluorescence filter (absorption filter) before being guided to a detector such as an eyepiece lens or camera.

Fluorescence imaging made significant advancements thanks to the Nobel Prize in Chemistry awarded in 2008 to three researchers: Professor Osamu Shimomura, Professor Martin Chalfie, and Professor Roger Y. Tsien. The prize recognized their discovery and development of the green fluorescent protein (GFP). GFP is a protein isolated from the bioluminescent jellyfish. Professor Shimomura was the first to successfully isolate GFP from jellyfish after observing that it emits green light when exposed to ultraviolet radiation. Subsequently, Professor Martin Chalfie contributed to understanding the fluorescence emission mechanism and successfully expressed GFP within living cells using genetic engineering techniques. Additionally, Professor Roger Y. Tsien elucidated the molecular mechanism of GFP chromophore formation, allowing the creation of artificial fluorescent proteins that emit various colors beyond green. This breakthrough enabled the expression of different colored fluorescent proteins within living organisms, facilitating simultaneous tracking of multiple biological phenomena, including the analysis of interactions between different proteins.

A fluorescence microscope is a type of microscope used for imaging cellular structures through fluorescence. A sample labeled with a fluorescent dye or protein is irradiated with excitation light, and the fluorescence emitted from the sample is focused by an objective lens and photographed by a camera.

Between 1962 and 2004, in the United States, Wratten life expectancy was at its lowest point in 1994, and highest in 1972. The average life expectancy for Wratten in 1962 was 79, and 55 in 2004.

Fluorescence imaging is an imaging technique that visualizes cells and molecules by fluorescently labeling them using fluorescent dyes, fluorescent proteins, and NV centers. Generally, cells and molecules are colorless and transparent, so they cannot be observed as they are. There are various staining methods other than fluorescent labeling to visualize cells; however, many of them can damage the cells. Fluorescent dyes, fluorescent proteins, and NV centers used in fluorescence imaging can label cells while they are alive, enabling live cell imaging of organisms. This allows us to obtain various information such as cell structure and function, and molecular interactions. Fluorescence imaging has become an important tool in the development of biology.

English (Kent):: probably a variant of Ratten from Old French raton ‘rat’ an unflattering nickname for someone thought to resemble a rat or possibly a metonymic occupational name for a rat catcher. possibly a habitational name from West Wratting in Cambridgeshire. The placename means ‘place where crosswort grows’ from Old English wrætt ‘crosswort’ + the placename forming suffix -ing.
