Quick and easy: An efficient approach for a direct observation of a thermally induced phase transition of a responsive polymer film on gold surfaces is described (see schematic). Voltammetric measurements show that the peak current and the peak separation for a small redox couple are particularly sensitive to the conformational change of the polymer film and allow its phase transition detection.
