(a) Absolute wavelength shift values and (b) intensity peak variations for each SV concentration and corresponding Langmuir isotherm for device. The error bars represent the standard deviation of blank measurements and wavelength shifts are taking into account resolution of the spectrometer ±0.25 nm and ±70 counts for intensity measurements.
