The invention discloses an
aspirin-based carbon
quantum dot and application thereof in aspects of
cell imaging and anti-inflammatory treatment, belonging to the technical field of nano-drugs. The invention in particular relates to a carbon
quantum dot with strong fluorescent properties prepared from a hydrazine
hydrate solution by utilizing a
microwave heating method under the condition that
aspirin dissolution is promoted. The carbon
quantum dot prepared by the method is very stable under hyper-salt concentration and physiological pH conditions, blue-
fluorescence is maintained, the carbon
quantum dot can enter the
cell nucleus, and the cells are effectively traced; and meanwhile, the original anti-inflammatory effect of
aspirin is remained, and inflammatory cells can be effectively inhibited in an acute
inflammation model constructed by utilizing carrageenin. In addition, the prepared aspirin carbon
quantum dot is low in
toxicity and does not influence
liver and kidney functions and organs such as the heart, liver,
spleen and
kidney in in-vivo application, and the aim that the nanometer material has dual effects of diagnosis and treatment can be achieved.
