 | | |  Plasmon-enhanced Fluorescence Spectroscopy Plasmon-enhanced fluorescence spectroscopy is a useful tool for imaging cells and other samples on a single-molecule level. This method poses several advantages over conventional fluorescence microscopy. | |

 | | |  When a molecule absorbs light, electrons in its constituent atoms become excited and are promoted to a higher energy level. When electrons in this excited state lose energy and return to the ground state, they release this energy in the form of heat or radiation. Light emitted during this process is known as fluorescence, and the molecules that show this activity are called fluorophores. | | | | |  Fluorescence microscopy is a common laboratory tool used to investigate the physiology of different cells. Specific wavelengths of light are shone onto cells in a sample, where the light is absorbed by molecules called fluorophores. | | | | |  In fluorescence microscopy, a specimen emits energy when activated by light of a certain wavelength. Some substances such as chlorophyll and some minerals will do this naturally, while others will need the help of other chemical triggers. | |
