Physical parameters of synthesized particles: size, the parameter characterizing poly-dispersity in size (PID), excitation/emission fluorescent maxima, fluorescent brightness, the zeta potential, and the number of folate molecules per single nanoparticle. For commercially available dyes were used to demonstrate the assembly of CA-dots fluorescent in the entire UV-VIS-NIR spectrum. Stilbene 420 (blue), Rhodamine 560 (green), Tracer Yellow (yellow), Methylene Blue (red/NIR) were used for encapsulation. Data for particles covered with PEG and PEG+folate are shown. Brightness relative to quantum dots was calculated for 1 QD450 41 (brightness 1 × 105 M−1 cm−1), 2 QD525 42 (brightness 1.3 × 105 M−1 cm−1), 3 QD585 42 (brightness 3.05 × 105 M−1 cm−1), QD705 43 (brightness 1.2 × 106 M−1 cm−1 ).
