(E’’) XPS survey spectrum of MMIP11 and (F’’) that of MNIP11, showing characteristic peaks of B, C, N, O, Si, and Fe. The increase in boron (B 1 s) signal intensity and atomic percentage relative to Fe₃O₄@SiO₂–NH₂@GA@APBA confirms successful incorporation of the boronic-acid functional monomer and the expected surface composition of the imprinted and non-imprinted polymers. The atomic concentrations and intensity values obtained from the spectra are summarized in the tables below each spectrum.
