ABSTRACT
Direct synthesis of carbon dots on uniform mesoporous nanospheres is an ideal way to impart fluorescence properties to the nanomaterials and retain its original uniformity. Carbon dot-based nanospheres with high quantum yield (aqueous solution, 89.3%) were synthesized by the one-step hydrothermal treatment of sodium citrate and dendritic silica spheres grafted with N-ß-(aminoethyl)-γ-aminopropyltrimethoxysilane. Its excellent chemical properties such as fluorescence, stability, homogeneity and dispersion enable it to achieve a sensitive, specific, rapid and low-cost detection of anthrax protective antigen when used as a signal for immunochromatography.
