A label-free thrombin photoelectrochemical aptasensor based on structure-switching in G-quadruplexes

In this work, an Au/GaN photoelectrode was prepared by sputtering a 30.0-nm–thick gold film on an n-type gallium nitride (GaN) surface. Guanine (G) was used as a hole trap in photoinduced charge separation due to its lowest oxidation potential and because it could be easily oxidized among the five c...
