Description

Nile red is a fluorescent dye that has a long history of use in various scientific fields. Its synthesis involves a multi-step process that starts with the condensation of 1-aminoanthraquinone with 2-chloro-4-nitrophenol, followed by a reduction and methylation. Nile red exhibits a unique characteristic of fluorescence enhancement upon binding to hydrophobic environments, making it a versatile tool for studying lipid-rich compartments in cells and tissues. This property has led to its widespread use in fluorescence microscopy, flow cytometry, and other imaging techniques for visualizing lipid droplets, membranes, and other hydrophobic structures. Furthermore, Nile red has proven valuable in studying various cellular processes, including lipid metabolism, lipid storage, and membrane dynamics. Its ability to sense changes in lipid content and organization within cells and tissues has made it a crucial tool in studying lipid-related diseases, such as obesity and atherosclerosis. Nile red is also used in environmental science to assess the presence and distribution of oil spills and to investigate the bioaccumulation of hydrophobic pollutants in organisms. This compound's versatility and sensitivity to hydrophobic environments make it a valuable tool in diverse research fields.'

Effects

The Nile red (NR) method has been extensively utilised to determine lipid phenotypes of yeast cells via microscopic means. Nile red has previously been used to screen for polyhydroxybutyrate and fatty acid esters. This is the first report of screening for recombinant bacteria making hydrocarbons or ketones.
