Fig. 3. Measurement of response/recovery time and repeatability of MNHM sensor.

Fig. 3.

Comparison of (A) response time and (B) recovery time of various resonators. The ratio of real-time intensity ΔI to the intensity in the equilibrium state ΔImax at the resonant wavelength was measured. Black, HM; orange, MNHM-OLA; red, MNHM-SCN; green, MHM. (C) The repeatability test of MNHM-SCN was conducted by measuring real-time intensity under two repeatedly changed states of RH 20 and 80%. Each state was maintained for 10 s and repeated 60 times. Concentration of the chitosan solution, 2%. Spin-coating speed, 2500 rpm.
