Abstract

The invention discloses a method for constructing ordered aggregates by carbon quantum dots and a surfactant. According to the method, negative carbon quantum dots with carboxyls outside is prepared by utilizing a byproduct, namely, carbon dust, in a process of producing fullerene by treating a mixed acid of HNO3 and H2SO4; the ordered aggregates, such as vesicles and honeycomb structures, are prepared by the negative carbon quantum dots and a cationic surfactant through an ion self-assembling method. The ordered aggregates by the carbon quantum dots are more stable in structure and are endowed with fluorescent properties. Therefore, the ordered aggregates which are constructed by the carbon quantum dots and the surfactant together have potential application value in the aspects of biomarkers, medicament delivery and the like.

Description

technical field [0001] The invention relates to a method for constructing ordered aggregates with carbon quantum dots and surfactants, belonging to the field of new materials. Background technique [0002] The use of liposomes, traditional surfactants, polymers, etc. to construct ordered aggregates has been very mature. However, with the increasing requirements for the function, structure and stability of aggregates, the use of nanoparticles to construct ordered Aggregates have received extensive attention from researchers. There are usually two methods for constructing ordered aggregates of nanoparticles, template method and self-assembly method. Among them, in order to make nanoparticles have amphiphilicity, the self-assembly method usually grafts block copolymers or mixed homopolymers on the surface of nanoparticles (C. Yi, S. Zhang, K. T. Webb and Z. Nie, Acc. Chem. Res ., 2017, 50,12-21; J. Song, G. Niu and X. Chen, Bioconjugate Chem ., 2017, 28, 105-114). But this...
