(a) Reflectance spectra from pNIPAm-co-BAAc etalons at the indicated temperatures at pH 3. (b) Peak position as a function of temperature. Data points in (b) are average of three devices and error bars represent the standard deviation. (c) Temperature cycling of pNIPAm-co-BAAc etalons between 25 and 41 °C at pH 3. (d) Temperature response of a pNIPAm-co-BAAc etalon at (Ο) pH 10 and (□) pH 3, well above and below the pKa of BAAc, respectively.
