Figure 1

Remnant fraction of active maleimides on silica/APTES/PMPI supports as a function of storage under 10 mM sodium phosphate, 0.1 M NaCl, pH 7.0. Filled squares and solid line: coverage of 1.1 PMPI/nm2 and 0.9 APTES/nm2, representing a fully converted APTES layer. Open circles and dashed line: coverage of 0.8 PMPI/nm2 and 1.3 APTES/nm2, representing a partially converted APTES layer. Asterisks and dotted line: 0.17 μM solution of BM(PEO)4. The lines are guides to the eye. All points represent an average of two measurements.
