TEMPO-oxidized cellulose nanocrystals (TO-CNC) were modified by covalent EDC/NHS coupling of luminescent, water-dispersible carbon dots (CDs). The prominent properties of CDs include stable photoluminescence, hypotoxicity and excellent biocompatibility which are desirable features for example in biological systems and bioimaging applications. Quartz crystal microgravimetry with dissipation monitoring (QCM-D) and surface plasmon resonance (SPR) were used to investigate the attachment of CDs on TO-CNC. Moreover, atomic force microscopy (AFM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were applied to characterize the main morphological features of the produced bio-hybrid materials. Main results and possible applications for such systems will be discussed.
