• uniform two-dimensional nanocarbon films, so-called carbon nanosheets, with ca. 10 nm thickness with dispersed nanopore structural motifs. The electrical conductivity of the transferred film was significantly increased after the thermal carbonization process. Nitrogen-doping was carried out simply by

• , using the bottom-up approach, we prepared C-dots based on the thermal carbonization of a mixture of nitrogen-containing organic compounds, ethyleneglycol bis(2-aminoethyl ether)-N,N,N′,N′-tetraacetic acid (EGTA) and Tris, thus providing them not only with surface hydroxy but also with amino groups

• running costs and high investment for their synthesis, the use of C-onions for analytical applications is still unexplored. Here, we describe the synthesis and characterization of C-nanoparticles obtained by thermal carbonization at 240 °C of tomatoes, carrots and tree leaves samples as C-source in

• C-NPs produced by the one-step thermal carbonization of tomatoes. For C-dots, a featureless reflection band centered at 2θ = 21.68° corresponds to the diffraction of graphite [002] crystal planes and a weak broad peak at about 2θ = 43° corresponds to the {100/101} set of crystal planes [24] of
