A) Tethered fluorophore-quencher complexes utilize fluorophore-quencher pairs that primarily undergo contact quenching. This enables an aptamer binding event to reduce quenching and turn on fluorescence. B) Fluorophore-quencher pairs are constructed with modern fluorophores linked (usually via PEG) to a quenching moiety.
