C60 fullerene as a bacterial biosensor (Biosensors 2019)

Authors use a bacterial biosensor (E. coli MG1655 pKatG-lux) to characterise whether C60 fullerene acts as an antioxidant or pro-oxidant in a living system. The conclusion is time- and dose-dependent: C60 is antioxidant in the first 15 minutes (and prolonged at 10⁻⁹ g/L), pro-oxidant after 50 minutes. A useful nuance against blanket claims that fullerenes are uniformly beneficial, the molecule's biological action depends on concentration and exposure time.

Edited 2026-05-03, source audit. Cited sources verified to exist; no fabricated sources detected. Where the audit could directly read the source (live English-language papers, open Russian academic articles), claims were compared against the source content and corrections applied above. Where sources were paywalled or geo-blocked at audit time, bibliographic plausibility was verified via parallel routes (publisher index pages, PubMed/PMC mirrors, cross-citations) but the source content itself was not always directly read.
