Abstract
A real-time method employing a portable peptide-containing potentiometric biosensor, can directly detect and/or quantify bacterial spores. Two peptides for specific recognition ofandSterne may be immobilized by a polysiloxane monolayer immobilization (PMI) technique. The sensors translate the biological recognition event into a potential change by detecting, for example,spores in a concentration range of 0.08-7.3×10CFU/ml. The sensing method exhibited highly selective recognition properties towardsspores over other kinds of spores. The selectivity coefficients of the sensors for other kinds of spores are in the range of 0-1.0×10. The biosensor method not only has the specificity to distinguishspores in a mixture ofand(.) Kurstaki spores, but also can discriminate between live and deadspores. Furthermore, the sensing method can distinguish aAfrom otherstrain. Assay time may be as low as about 5 minutes for a single test. Rapid identification ofSterne andΔAmes was also provided.
