Method for linking biomolecules to BSA-coated porous SiO2. (a) A PSiO2 film is prepared. (b) The sample is submerged in a solution of BSA in pH 4.0 buffer, and the pore walls become coated. (c) Excess BSA is rinsed off in PBS buffer (pH 7.4) and the peptide KAA is attached to the adsorbed protein. (d) Vancomycin is introduced and binds to the attached KAA.
