Fluorophores are molecules that can absorb light at a specific wavelength and then re-emit it at a longer wavelength. This property makes them useful in various scientific applications, particularly in biological imaging and fluorescence microscopy. When excited by light, fluorophores emit bright colors, allowing researchers to visualize and track specific cells or proteins. These compounds are commonly used in biotechnology and medical diagnostics to label biological samples. Different fluorophores have unique emission spectra, enabling multiple targets to be distinguished simultaneously in a single sample. Their versatility and sensitivity make them essential tools in modern research.
