The invention relates to a method for simultaneously detecting three antibiotic residues including streptomycin, chlorampenicol and tetracycline based on nucleic acid aptamers and quantum dots and belongs to the technical field of analytical chemistry. Three-section complementary cDNA 1 sequences are designed and synthesized and are complemented with three antibiotic aptamers DNA sequences and are further complemented with respective capturing probe DNA sequences of three antibiotics and complementary cDNA 2 sequence part. The three cDNAs 1 are first hybridized with aptamer DNAs supplemented with each other to form double-stranded DNAs.
