文摘
- •
Incorporation of IL effectively improves sensitivity of GNS/Pd toward glucose.
- •
BMP–DCA IL effectively improves sensitivity of GNS/Pd toward ascorbic acid.
- •
Selective detection is achieved using a non-enzymatic electrode with designated IL.
- •
GNSs can render an aligned cation/anion orientation in the adsorbed IL film.
- •
IL anions occupy the topmost electrode surface, determining the selectivity.
