abstract = "Surface-enhanced absorption (SEA) has been used to monitor interactions of biomolecules and to observe structural changes of polymers. Such interactions of biomolecules are of interest in high-throughput
screening and diagnostics. The structural changes of synthetic polymers can be exploited in optical sensorics. Based on SEA we have developed a technique that enables us to transfer the interaction of polyelectrolytes
between two flat, solid surfaces into a visible color change, exploiting nanoscopic metal clusters. The polyelectrolytes are coated onto electrochemically oxidized aluminum, glass, and polycarbonate substrates.
The change of surface color is monitored with a flat-bed scanner, and the interactions are analyzed kinetically. The results are interpreted with regard to adhesion, surface tension, electrostatic interactions,
and miscibility.
