Recently, it was discovered that 2D COF can adsorb single-stranded DNA (ss-DNA) efficiently as well as usefully to quench fluorophores. These properties make it possible to prepare DNA-based optical biosensors using 2D COF. While practical analytical applications are being demonstrated, the ...

Therefore, a method for detecting MiR-205 based on 2D COF nanosheets and fluorescent oligonucleotide probe was constructed and investigated in this study. The 2D COF nanosheet quenches the fluorescence of the fluorescent single-stranded DNA (ss-DNA) probes through fluorescence resonance energy transfer...

It was found that shorter DNAs adsorbed more rapidly and bound more tightly to the surface of 2D COFs. Many different factors ...
