7830 | 604 | GO/AuNPs | TEM | From the inserted TEM, it can be seen that the small amount of spherical nanoparticles with the particle size of about 30 nm were uniformly dispersed and embedded on the surface of GO. The graphene sheet is covered with tightly compressed spherical nanoparticles with particle size of about 30 nm, which should be gold nanoparticles. |

Human serum samples were taken from Xi'a University of Science and Technology Hospital. As the normal content of human blood glucose is 3.9–6.1 mmol/L [38], before the test, the collected serum samples need to be diluted to meet the requirements of this method after centrifugation. The glucose test results are shown in Table 2. For three different test samples, the detection results from this method are not substantially different from those given by the hospital. |
