A novel nonenzymatic electrochemical glucose sensor modified with Ni/Al layered double hydroxide

- The preparation method of flower-shaped Ni/Al layered double hydroxide (LDH) is quite simple.
- The Ni/Al-LDH has great adsorption capacity owing to its flower-shaped nature.
- The very good linear relationship toward glucose can be obtained in two regions: 1-100 μM and 0.5-21 mM.
- The sensor has a detection limit of 0.11 μM.
- The sensor possesses high sensitivity, good stability and excellent repeatability.
- The sensor shows a great potential for practicable applications.
