Presently, the technologies associated with using waste materials for the fabrication of newer useful materials have been greatly advanced. For the same purpose, a possible sustainable approach is described for the utilization of globally available dirty dangerous material, known as black carbon (BC), in the form of particulate diesel soot. From the black diesel particulate matter, onion-like nanocarbons (ONC) have been isolated followed by their surface functionalization to yield their amine-functionalized water-soluble version as ONC-NH 2 , which exhibits a high quantum yield value of ∼20%. Concerning the synthetic protocol, the potential associated with the presented report reveals that these ONC were used without being explicitly synthesized. These were just isolated from the diesel soot, which on amine functionalization have been converted to an efficient, biocompatible fluorescent probe for the imaging of cancer (HeLa) cells and selective sensing of toxic chromium Cr(VI) in water. The detailed surface functionalization by the amine molecules in ONC-NH 2 , which make them readily soluble in aqueous media, is investigated using several spectroscopic techniques such as XPS, NMR, and FTIR.
