Nanoparticles (07/10/17 22:30:32)
Well, a red blood cell is about 6000 nm in diameter. A thrombocyte is about 1000 nm in diameter. A bacterium - Eschericia coli is about 1000 x 1000 x 2000 nm
Anyone using caramel (sugar colour) for their sauces? That's carbon nanoparticles
"We report the finding of the presence of carbon nanoparticles (CNPs) in different carbohydrate based food caramels, viz. bread, jaggery, sugar caramel, corn flakes and biscuits, where the preparation involves heating of the starting material. The CNPs were amorphous in nature; the particles were spherical having sizes in the range of 4–30 nm, depending upon the source of extraction. The results also indicated that particles formed at higher temperature were smaller than those formed at lower temperature. Excitation tuneable photoluminescence was observed for all the samples with quantum yield (QY) 1.2, 0.55 and 0.63%, for CNPs from bread, jaggery and sugar caramels respectively. The present discovery suggests potential usefulness of CNPs for various biological applications, as the sources of extraction are regular food items, some of which have been consumed by humans for centuries, and thus they can be considered as safe."
as a beginning.
Then we can go further, but not today.
