“…[ 18,19 ] The oxygenated surfaces functional moieties on the CDs have changed the surface architecture and sizes of particles, allowing the quantum confinement effects, which appears when the CDS radius is less than the exciton Bohr radius. “Electronic bandgap transitions of conjugated‐domains, surface defect states, local fluorophores, and element doping all influence fluorescence color of CDs.” [ 20 ] When photons stimulate CDs, electrons move to excited states and ultimately return to the equilibrium states/ground state. The extra energy is released via the radiative process, which results in light emission, photoluminescence (PL).…”

“…On the contrary, a study showed that amino capped CDs synthesized via solvothermal treatment and purified by size exclusion chromatography presented no alteration in the photoluminescence band maxima as compared to crude CDs. [ 20 ] They proposed a synthesis method for CDs that do not require purification, as the unreacted species in crude CDs do not interfere with nitrite testing.…”

Carbon dots (CDs) correspond to carbon‐based materials (CBM) with sizes usually below 10 nm. These nanomaterials exhibit attractive properties such us low toxicity, good stability, and high conductivity, which have promoted their thorough study over the past two decades. The current review describes four types of CDs: carbon quantum dots (CQDs), graphene quantum dots (GQDs), carbon nanodots (CNDs), and carbonized polymers dots (CPDs), together with the state of the art of the main routes for their preparation, either by “top‐down” or “bottom‐up” approaches. Moreover, among the various usages of CDs within biomedicine, we have focused on their application as a novel class of broad‐spectrum antibacterial agents, concretely, owing their photoactivation capability that triggers an enhanced antibacterial property. Our work presents the recent advances in this field addressing CDs, their composites and hybrids, applied as photosensitizers (PS), and photothermal agents (PA) within antibacterial strategies such as photodynamic therapy (PDT), photothermal therapy (PTT), and synchronic PDT/PTT. Furthermore, we discuss the prospects for the possible future development of large‐scale preparation of CDs, and the potential for these nanomaterials to be employed in applications to combat other pathogens harmful to human health.
