with a droplet microfluidic system in order to perform the analysis in
a high-throughput manner with small sample consumption. Moreover,
compartmentalization in droplets prevented the adsorption of
analytes on the electrode surface. Accordingly, no washing and drying
steps between consecutive runs were required, resulting in minimization
of analysis time compared with batch-wise electrochemical
sensing methods. Therefore, advantages of a droplet system, including
rapid mixing, no sample dispersion and adsorption, low sample consumption,
portability and high throughput analysis, enhance the
analytical performance of the chip-based GlcN sensor
