Single stranded DNA sequences can be detected by target assisted exonuclease III-catalyzed signal amplification fluorescence polarization (TAECA-FP). The method offers an impressive detection limit of 83 aM within one hour for DNA detection and exhibits high discrimination ability even against a single base mismatch.
