Table 2 Detection of glucose in human serum

From: Sensitive Nonenzymatic Electrochemical Glucose Detection Based on Hollow Porous NiO

Sample Measured by medical equipment (mM) Measured by NiO (mM) RSD (%) Added (mM) After adding (mM) Recovery (%)
1 3.6 3.5 2.85 5.0 8.4 98
2 5.1 5.2 2.93 5.0 9.8 92
3 7.6 7.5 3.84 5.0 12.6 102
  1. All the concentration tests and RSD calculations are of five independent measurements
  2. Recovery = (after adding − before adding)/added × 100%
