Abstract
•Highly photoluminescent carbon quantum dots (CQDs) were synthesized using citric acid and polyethyleneimine.•The CQDs were conjugated to anti-aflatoxin M1 (AFM1) antibody for nanosensor development.•The nanosensor displayed a LOD of 0.07 ng/mL for AFM1.•CQDs-based lateral flow assay is demonstrated for AFM1 detection in milk.
