Abstract

We developed a facile and effective route to synthesize GQDs for bioimaging by using starch as a precursor. The reactants consist of only starch and water. Furthermore, the products are only GQDs, water, and carbide precipitate. Thus, the complicated post-processing steps are avoided. The present work is the first report of the synthesis of GQDs from a high molecular weight polymer.
