"Foodborne nanoparticles (NPs) have drawn great attention due to human health concerns. This study reports the detection of the presence of fluorescent NPs, about 5 nm, in two of the most popular beverages, Coca-Cola (Coke) and Pepsi-Cola (Pepsi). The NPs contain H, C and O, [three elements with a tunable emission] and with a quantum yield of 3.3 and 4.3% for Coke and Pepsi, respectively. The presence of sp3-hybridized carbon atoms of alcohols and ethers bonds was confirmed by NMR analysis."
"The biodistribution study in major organs indicated that the NPs were easily accumulated in the digestive tract, and they were able to cross the blood-brain barrier and dispersed in the brain."
