Biological and catalytic applications of green synthesized fluorescent N-doped carbon dots using Hylocereus undatus

Miscanthus grass-derived carbon dots to selectively detect Fe3+ ions

“…13 In many cases, sustainable materials are derived from biobased precursors. [14][15][16][17][18][19] Such carbon sources can be generalized under the following categories: fruits/vegetables, food/beverage wastes, animal/human derivatives and plant/agricultural biomass materials. 13 The use of agricultural biomass and wastes has a positive impact on the environment as the materials repurpose waste into value-added products.…”

Biomass‐Derived Carbon Dots and Their Applications

“…The average size of the synthesized BCDs is approximately 7 nm, and their fluorescence QY was determined to be 13% using quinine sulfate as a reference fluorophore. Arul et al . reported preparing fluorescent N‐doped BCDs by using dragon fruit as a carbon source and hydrothermal treatment at 180 °C for 12 h. The BCDs were spherical, and they have an average diameter of 2.5 nm.…”

“…The photocatalytic activity of the TiO 2 ‐BCDs composite is approximately 2.5 times greater than that of the TiO 2 nanofibers. Arul et al . reported a simple hydrothermal route for the synthesis of fluorescent BCDs using Hylocereus undatus extract as the carbon source.…”

Natural carbon-based quantum dots and their applications in drug delivery: A review

“…However, these semi conducting quantum dots witness toxicity problems because of the presence of heavy metals, and therefore many of the clinical studies are interrupted. Even at low doses, they tend to exert a harmful effect on human beings and environment due to the involvement of heavy metals in their preparation [ 8 ]. These limitations triggered the development of CDs and eventually, Xu et al discovered CDs possessing fluorescent properties, during the separation and purification of carbon nanotubes.…”
