Sensitive Electrochemical Detection of Tryptophan Using a Hemin/G-Quadruplex Aptasensor
In this study, we design an electrochemical aptasensor with an enzyme-free amplification method to detect tryptophan (Trp). For the amplified electrochemical signal, the screen-printed electrode was modified with dendritic gold nanostructures (DGNs)/magnetic double-charged diazoniabicyclo [2.2.2] oc...
