Structure of the dataset:

The structure of this dataset is represented by the following description.
Fig. 1 (tiff) Schema of the preparation of optical fiber based sensor for in-situ estimation of enzyme activity and its operation: 
		A, B - plasmon-induced grafting of glycoside chemical moieties (A, B) and their subsequent enzyme-induced cleavage 
		C, D - both leading to the shift of the wavelength position of plasmon absorption band, which can be red in the light-reflection mode.
