FULL VIDEO start to finish of Pepsi Max.

(from Chinahh, 2018)
"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."

NMR = nuclear magnetic resonance
carbon atoms = carbon quantum dots

(2021)"Fluorescent molecules, such as fluorescent proteins, quantum dots, and organic dyes, can also be used to realize a wavelength‑selective optical interface. Organic dye molecules have been used as nanotransceiver antennas for FRET‑based molecular nanonetworks. They act as single molecular optical interfaces that receive optical control signals from an external source and non‑radiatively transmit them into a FRET‑based nanonetwork."

"Optogenetics is an elegant approach of precisely controlling and monitoring the biological functions of a cell, group of cells, tissues, or organs with high temporal and spatial resolution by using optical system and genetic engineering technologies."
