Figure 12

Response time of the humidity sensor of the (PVS/PDDA)2(AuNPs/arg-M13)4 film on a quartz substrate. a) SPR spectra of the film in air with 98% RH and at a different time after being switched to air with 70% RH. b) Enlargement of the absorbance peaks in (a). The time on the arrow in (b) shows the time at which the SPR spectrum of the film was recorded after the film was switched from 98% to 70% RH.[160]
