We here report that the formation and breakdown of an intramolecular cytosine-thymine (CT) motif DNA triple-helix can be performed repeatedly, quickly and independently of its local concentration without performance reduction over successive cycles; as a consequence, we propose that this set of characteristics makes the DNA duplex-triplex transition an ideal candidate to power simple nanometer-scale devices capable of maintaining effective performance regardless of their local concentration.

In the present study, the experimental data on the pH-induced formation of the i-motif structure in the nucleotide sequence 5'-CCTTTCCTTTTCCTTTCC-3' (25oC, pH 3.3-8.9) obtained by spectroscopic techniques, such as UV molecular absorption and circular dichroism, has been analysed using the chemometric soft modelling-based MCR-ALS approach and the hard modelling-based matrix method.
