Water-soluble CD samples can be easily filtered and dialyzed. The process relies on the diffusion of small fluorescent molecules from a higher concentration region to a lower concentration area across a semipermeable membrane. During this process, the as-synthesized CDs are dissolved in deionised water and dial
