Chiral Carbon Dots Synthesized on Cellulose Nanocrystals
Hybrid nanoparticles composed of cellulose nanocrystals (CNCs) and carbon-dots (C-dots) have promising applications in chemistry, biology, and nanomedicine, owing to the photoluminescence, sensory properties, and cytocompatibility of C-dots, and chirality, cytobiocompatibility, and high cellular uptake of CNCs. The possibility of circularly polarized luminescence in such nanoparticles is particularly attractive. Herein, scalable and straightforward hydrothermal synthesis of nitrogen-doped fluorescent C-dots under reflux condition by using CNCs as a carbon source and chiral substrate is reported. Under ultraviolet irradiation, hybrid C-dot/CNC nanoparticles exhibit stronger emission of left-handed, than right-handed, circularly polarized light, with high dissymmetry factor up to 0.2. The nanoparticles are biocompatible: the normalized proliferation index above 100% is determined for MCF 7 cells cultured in the suspension of C-dot/CNC nanoparticles. These hybrid nanoparticles can find applications as biotags for labeling, sensing, and therapeutics and as building blocks of photoluminescent cholesteric CNC films with photonic applications.
