Contact angle measurements were used to evaluate the success of the functionalization of the silicon oxide surfaces. Table in the Supporting Information exhibits the values obtained for different surfaces, and Figure (Supporting Information) also shows the corresponding contact angle images. The non-functionalized silicon oxide surface (SOS) exhibited hydrophilicity with a contact angle of 39°±3°. After functionalization with the azide linker (SOS-N3), the contact angle increased to 90°±2°, indicating enhanced hydrophobicity. After conjugation, a reduced contact angle of 72°±3° was found for Bdpy1 conjugated surface (SOS-Bdpy1) and 68°±2° for Bdpy2 conjugated surface (SOS-Bdpy2), confirming successful Bdpy1 and Bdpy2 conjugation.
