Figure Lengend Snippet: Switching and protein binding capabilities of PVME 50 –PNiPAAm 40 –PVMEMA 10 layers. (a) Thermo-responsive switching in PBS was reversible with almost no hysteresis. (b) LN/CS binding moderately affected the switching behavior in PBS. (c) Exposure to serum containing medium at 37 °C proved the stability of covalently versus non-covalently attached LN. Mean ± sd of relative fluorescence intensity values; n = 2 (see figure S2 for corresponding RGD data).
Article Snippet: Relative fluorescence intensities were measured with a fluorescence laser scanner (FLA-5100; FUJIFILM Europe GmbH, Düsseldorf, Germany) using an excitation wavelength of 473 nm to check for possible protein displacement, i.e., insufficient attachment of the biofunctional molecule.
