Table 1. Characteristics of the Fabricated Clay/AuNPs/AChE Biosensorsa.
types of clay | AuNP loading (wt %) | weight of adsorbed water on the surface (wt %) | active unit of AChE per electrode | current response (μA) |
---|---|---|---|---|
Kaol/AuNPs | 3.11 | 0 | 0.129 | 15.02 ± 0.83a |
Mt/AuNPs | 1.62 | 3.34 | 0.212 | 21.89 ± 0.39b |
Bent/AuNPs | 2.17 | 3.56 | 0.176 | 18.86 ± 0.56c |
Sep/AuNPs | 0.96 | 7.53 | 0.137 | 15.94 ± 0.29a |
Statistical analysis results show that values of the same letter (a, b, c) within the same column are not significantly different and vice versa for values of different letters within the same column, judged from the Fisher LSD method and 95% confidence intervals for each pair of parameters.
