This may be the first documented case of carbon quantum dots showing repellent effects. The mechanism is not yet understood — hypotheses include DNA damage via cell membrane penetration, emission of insect-repelling light wavelengths, or photocatalytic effects. Compared to conventional chemical repellents like DEET, these bio-derived quantum dots could be cheaper due to low-cost waste feedstocks and potentially safer due to their natural origin. Further research is planned to clarify the mechanism and evaluate broader agricultural applications. ## Full article daily.dev links to this article rather than hosting it.
