I draw the schematic diagram of modification of ITO$-$APTES$-$rGO substrate, but my doctor said that i have to reverse the NH$2$ and O$-$Si$-$O$-$rGO, how? Draw for me the correction.Ps:As we know the amine $(-$NH$2)$ groups present in the APTES layer formed electrostatic bonds with the ITO substrate, resulting in the strong adhesion between the APTES$-$ rGO composite film and ITO substrate.
