Overwhelming evidence has been collected that links the data coming from solid\u2010state analysis (high\u2010resolution transmission electron microscopy (HRTEM), atomic force microscopy (AFM), and matrix\u2010assisted laser desorption\/ionization (MALDI) mass spectrometry (MS)) to that of solution (pulsed\u2010field gradient (PFG)\u2010NMR spectroscopy, time\u2010resolved fluorescence anisotropy (TRFA), and steady\u2010state\/time\u2010resolved fluorescence), allowing the establishment of an overall structural model for CDs. According to this model, the so\u2010called <jats:italic>carbon dots<\/jats:italic>, observed under HRTEM imaging, are in fact <jats:italic>supramolecular organized structures<\/jats:italic> dynamically assembled from small to medium\u2010sized molecular species when the solvent is removed to give the solid form. In this way, the imaged nanoparticles (TEM\/AFM) are not <jats:italic>covalently bound entities<\/jats:italic> formed during the synthetic process, but instead supramolecular entities formed by noncovalent interactions. These particles, if at all present in solution, have the form of loose associations of relatively small molecules. This study was conducted on CDs obtained from the hydrothermal carbonization (HTC) of a biomass waste (olive wet pomace).<\/jats:p>","DOI":"10.1002\/chem.202302955","type":"journal-article","created":{"date-parts":[[2023,11,9]],"date-time":"2023-11-09T08:28:19Z","timestamp":1699518499000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Are \u201cCarbon Dots\u201d Always Carbon Dots?
