Carbon Dots for Fluorescence Sensing Carbon dots are a newly developed form of fluorescent carbonaceous substance that shows controllable photoluminescence and strong biocompatibility. In lignocellulose, lignin is a type of aromatic polymer having a large concentration of carbon and numerous oxygen-containing functional groups and may be employed as a source for carbon-based materials.
Encapsulating carbon dots inside a matrix stabilizes carbon dot fluorescence and allows for real-time and portable detection. Research Methodology The team utilized an eco-friendly deep eutectic solvent framework as a pretreatment platform to isolate lignocellulose biomass residual poplar sawdust. By producing a confinement effect, the internal hydrogen bonding among carbon dots and cellulose nanofibers could successfully stabilize the fluorescence of carbon dots.
