The proposed ECL mechanism in the Carbon-Dots system is outlined schematically in Fig. 16 and largely mimics known ECL mechanisms in semiconductor nanoparticles. In principle, surface states of the Carbon-Dots were believed to play a critical role in generation of the excited electronic state, subsequently relaxing to a lower surface energy state through light emission. Interestingly, the shorter wavelength luminescence observed by the researchers in the same Carbon-Dot samples was ascribed to presumably greater energy separation of core energy levels of the Carbon-Dots (Fig.

11). Similar relationship between curvature match/mismatch and cell killing was also recorded in case of the rod-shape P. aeruginosa bacteria (Fig. 11). In a broader context, this work might cast doubt on the premise that Carbon-Dots (and GQDs) are inherently non-cytotoxic as the carbon nanoparticles might still exhibit membrane disruption activity even towards mammalian cells. , DNA, RNA) could usher a plethora of new applications. In general, attachment of DNA or RNA to Carbon-Dots could be accomplished when Carbon-Dots display positive surface charge (as oligonucleotides are negative in physiological conditions).
