Superelastic N-centered carbon quantum dots: Synthesis and characterization
Original language description
Carbon quantum dots (CQDs) have highly promising properties for variety of applications as a new family member of carbon-based nanomaterials. In this paper, CQDs were synthetized by solvothermal method using nicotinamide as precursor. For the first time, we report on electron paramagnetic resonance (EPR) active CQDs with numerous unpaired N radicals at the edges of CQDs. Nanomechanical measurements revealed internal structure of CQDs that are more elastic than single wall carbon nanotubes (SWCNTs). Electrostatic force microscopy showed average amount of electrons in CQDs core and positive charge at the edges. Polymer nanocomposites based on CQDs were not cytotoxic and hemolytic whereas antibacterial testing shown good antibacterial activity. Reactive oxygen species production measurements indicated that nanocomposites were highly potent generators of reactive oxygen species with singlet oxygen yield of 0.68 and promising materials for application in biomedicine.
