Development of carbon quantum dot-based lateral flow immunoassay for sensitive detection of aflatoxin M1 in milk
Food Chemistry(2022)
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.
