Facile synthesis of fluorescent carbon nanodots from starch nanoparticles
Fluorescent carbon dots were synthesized by the carbonization of preformed native sago starch nanoparticles, followed by surface oxidation in an aqueous medium.

| description | Fluorescent carbon dots were synthesized by the carbonization of preformed native sago starch
nanoparticles, followed by surface oxidation in an aqueous medium. The morphology and particle sizes
of carbon nanodots (CDs) were observed to be very similar to starch nanoparticles that were used as
precursors. The particle sizes of CDs synthesized in this study were within the range 50–80 nm, which
were much larger than those of very tiny CDs (1–5 nm) previously reported. The CDs portrayed
fluorescent with constant emission wavelength peak at 430 nm when excited with various higher
energy photons. The non-shifting of the emission wavelength peak suggested that CDs prepared in this
study were highly homogenous and possessed mono-dispersed physiochemical properties. |
