However, as demand for these products has grown, so has the generation of waste, with vinasse emerging as the primary pollutant. This study investigates the potential of utilizing vinasse as a raw material to produce carbon dots (BioC-dots), a high-value product. Application of the synthesized BioC-dots in metal ion detection is yet to be explored. Luminescent nanocarbons (BioC-dots) were successfully synthesized from vinasse using a green synthesis method and characterized through transmission electron microscopy (TEM) imaging, UV\u2013vis spectroscopy, and photoluminescence spectroscopy, which revealed a quantum yield ranging from 2.5% to 19%. TG-DTA curves and FTIR spectra revealed a remarkable thermal behavior and main functional groups of the surface of nanocarbon. The interaction of metals with BioC-dots in solution demonstrated their potential as effective sensors for cobalt and zinc ions in aqueous environments, showing detection limits of 13.57 and 18.22 mmol L\u20131, respectively.<\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>Nanocircularity in Agriculture with BioC-Dots: Vinasse-Derived Carbon-Dots and Their Usage as Potential Metal Ion Sensors ACS OmegaVol 10\/Issue 33 August 16, 2025 https:\/\/pubs.acs.org\/doi\/10.1021\/acsomega.4c11597\u00a0 Ulisses N. de Morais Eralci M.
