The detection technique was optimized using short DNA sequences, then applied for a 92-mer from the Aspergillus gene aflR that codes a biochemical pathway of aflatoxin B1 production. Voltammetric detection of the specific Aspergillus DNA sequence is based on hybridization of adsorbed target DNA with a biotinylated probe and subsequent binding with streptavidin alkaline phosphatase conjugate. Such modified electrode surface of carbon paste electrode (CPE) is incubated in a buffer with an electrochemically inactive substrate (1-naphthyl phosphate). Alkaline phosphatase converts 1-naphthyl phosphate into 1-naphthol, which is determined by the selected voltammetric technique. The optimized procedure provided good differentiation between complementary and noncomplementary probes and also between potentially aflatoxigenic and non aflatoxigenic fungi of the genus Aspergillus."@en . . .
