KWEE, Yaung et al. Carbon Nanodots Derived from Natural Products. S.Afr.j.chem. (Online) [online]. 2021, vol.75, pp.40-63. ISSN 1996-840X.

This review highlights recent improvements, and present situations concerning the practical application of, natural products-based carbon nanodots (CNDs) in nanomedicine, sensors, drug delivery, bio-imaging, solar cells, photocatalysis and nano-encapsulation. CNDs are zero-dimensional carbonaceous nanomaterials that have recently drawn much attention because of their unique physicochemical properties, such as excellent biocompatibility and tunable photoluminescence, easy functionali-zation, solubility in water, dispersibility, and low toxicity. Additionally, they are environmentally friendly, abundant, easily accessible, and rich in multiple elements. Since CNDs derived from organic products have unique properties, we explored and found that the properties of CNDs may depend on the preparation method and the used precursors. This study also informs on the positioning of natural products in nanotechnology.

Keywords : Carbon nanodots; natural product; synthesis; applications.
