The i-motif DNA, which is formed from cytosine (C)-rich sequences at slightly acidic pH or even neutral pH, has been extensively investigated as a signpost and controller for the oncogene expression at the transcription level and as a promising material in nanotechnology. Using the fluorescence techniques such as FRET and the fluorescence quenching, thus, the visualization of the unique and reversible conformational switching of i-motif DNA triggered by the proton has been widely preformed for applying in the nanotechnology.
