Nile red (also known as Nile blue oxazone) is a lipophilic stain. Nile red stains intracellular lipid droplets yellow. In most polar solvents, Nile red will not fluoresce; however, when in a lipid-rich environment, it can be intensely fluorescent, with varying colors from deep red (for polar membrane lipid) to strong yellow-gold emission (for neutral lipid in intracellular storages).
Nile red (also known as Nile blue oxazone) is formed by boiling Nile blue with sulfuric acid. This produces a mix of Nile red and Nile blue. Nile red is a lipophilic stain; it will accumulate in lipid globules inside cells, staining them red. Nile red can be used with living cells.
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. Microplastics' effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
People with microplastics and nanoplastics in plaque lining a major blood vessel in their neck may have a higher risk of heart attack, stroke or death, new research suggests. Doctors found tiny ...
Microplastics are tiny pieces of plastic that are no larger than five millimeters (0.2 inches)—about the size of a single sesame seed—and form when larger plastics break down, either by ...
Microplastics can act as carriers for the transfer of POPs from the environment to organisms, also termed as the Trojan Horse effect. [210] [133] [134] Recent articles have also shown that microplastics can sorb emerging organic chemicals such as pharmaceuticals and personal care products.
Scientists have found microplastics deep in people’s lungs and even bloodstreams. Experts say more research is needed to understand the health consequences. Scientists know microplastics are in ...
Microplastics in the soil are a risk not only to soil biodiversity but also food safety and human health. Soil biodiversity is important for plant growth in agricultural industries. Agricultural activities such as plastic mulching and application of municipal wastes contribute to the microplastic pollution in the soil.
