Abstract: A super-molecular nucleic acid assembly,termed Triplex Nucleic Acids(TNAs),is formed between the third oligonucleotide strand and classical Waston-Crick base-pair-formed double strands through the non-classical Hoogsteen hydrogen bond at the major groove site. Among recently developed biosensors,TNAs-based sensing platforms have been attracting more attentions on account of the advantages of rapidity,simplicity,sensitivity,and reversibility. In this review,we generalized and exemplified different TNAs-based biosensors from their classifications,characteristics to applications. We also highlighted the development prospects of the TNAs biosensor.

Key words: triplex nucleic acid(TNAs), biosensor, comment
