Abstract: M71.00394 : Synthesis of carbon nanodots from caramelized glucose solutions
We investigated multiple possible methods of purification of glucose solutions . Glucose solutions were heated at 120 °C for a period of 48 hours to produce carbon nanodots. We found that dialysis combined with solid phase extraction preserved the photoluminescent properties of dissolved carbon nanodots, while eliminating measurable traces of other chemical byproducts, as measured by Fourier-Transform IR spectroscopy, Carbon-NMR, and Hydrogen-NMR.
