UV-vis spectral analysis of the synthesized Chi-AgNP, chitosan and AgNO3. The inset shows an image of the stabilized NPs and the modified electrodes. Sensing electrodes are formed by depositing 8 µl of the solution (inset) on glassy carbon. On drying, the particles are firmly adhered and do not detach even after several hours of incubation in PBS (inset).
