Gram scale synthesis of green fluorescent water-soluble onion-like carbon nanoparticles from camphor and polystyrene foam

Dubey, Prashant, Tripathi, Kumud Malika, Sonkar, Sumit Kumar·2014·RSC Advances

Abstract

Herein, we report a cost effective and simple method for gram scale synthesis of water-soluble onion-like carbon nanoparticles (wsOCNPs) using common carbonaceous sources like camphor and polystyrene foam. The synthetic methodology involves ambient burning of these carbon rich materials under an insufficient oxygenic atmosphere. Furthermore, the oxidative treatment of carbon soot (CS) imposes dense carboxylic group functionalization over the surface of wsOCNPs. The high degree of surface functionalization imposes a self-passivated fluorescence effect along with photostability, which makes the material a potential candidate for bio-imaging purposes. Surprisingly, these wsOCNPs show exceptional excitation wavelength independent fluorescence emission properties over a wide region of the visible spectrum.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
