Are there florescent nanoparticles in Pepsi and Coke?
A peer-reviewed 2017 study published in Nanotoxicology confirmed fluorescent nanoparticles roughly 5 nm wide are present in commercial Coke and Pepsi samples. The particles are real, documented, and entered living cells in subsequent testing. What remains contested is origin and intent — whether they are incidental processing byproducts or something more deliberate.
Evidence
- Researchers Shen Li and Mingqian Tan published findings online in December 2017 in the journal Nanotoxicology, reporting the first confirmed isolation of fluorescent carbon-based nanoparticles from commercial Coca-Cola and Pepsi-Cola.
- Cell and mouse biodistribution experiments showed the isolated particles entering living cells, accumulating in membranes and cytoplasm.
- A German consumer-watchdog review (Verbraucherrat, August 2026) confirmed the core study is real and not fabricated, while stopping short of endorsing any deliberate-contamination hypothesis.
- The particles measured approximately 5 nanometers, composed primarily of carbon, hydrogen, and oxygen, with nuclear magnetic resonance confirming alcohol- and ether-type carbon bonds.
- Similar carbon dots form spontaneously when sugars and organic compounds are exposed to heat — parallel research has identified them in baked goods and other processed foods.
