Summary of CD properties regarding the composition as shown by the sum formula, viability of cells after addition of 400 μg mL⁻¹ CD (incubation time 4 h, see SI for more details), size, optical data such absorption maximum (λ _max ^abs) and fluorescence maximum (λ _max ^fluo) with their respective decay times (τ _1–4) determined by global analysis (globally fitted data appear bold and underlined), ^[46] and redox potential such as oxidation (E _ox) and reduction potential (E _ox). It also gives information about the synthetic method applied for synthesis of the CDs that based on solvo‐thermal or hydro‐thermal treatment. Available is also a summary of reactions successfully pursued with each CD. SI gives more details about determination of data. Decay times that were not globally linked change with wavelength. SI gives data of each CD determined at different wavelengths.
