Cover Story: Carbon dots (CDots) are defined as small carbon nanoparticles with surface organic functionalization, a definition which is literally based on their description when CDots were originally discovered. However, a more popular approach to materialize the dot structure as defined has been to create the required nanocarbon domains via thermal carbonization of organic precursors, though the samples thus obtained are morphologically composite-like, more appropriately denoted as “nano-carbon/organic hybrids”. For the significant structural and morphological differences between classically synthesized CDots and the carbonization-produced hybrids, some of their optical spectroscopic properties are similar, but the photoinduced antimicrobial outcomes are dramatically different.
