Fig. 3. XPS spectra of AAO, MOF, and ATP/MOF/AAO. (a) Survey spectra of bare AAO, MOF and ATP/MOF/AAO. (b, c) The narrow spectra near the O1s peak for MOF and APT/MOF/AAO. (d) The narrow spectra near the P2p peak for MOF and APT/MOF/AAO. (e, f) The narrow spectra near the N1s peak for MOF and APT/MOF/AAO. The above results show that the aptamers were successfully grafted onto MOF to form APT/MOF/AAO.
