2.8.2 Glucose sensinG
The glucose was sensed by ZnO nanorod-functionalized HEMTs with glucose oxidase enzyme
localized on the nanorods, shown in Figure2.24. This catalyzes the reaction of glucose and oxygen
to form gluconic acid and hydrogen peroxide. Figure2.25 shows the real-time glucose detection
in PBS buffer solution using the drain current change in the HEMT sensor with constant bias of
250 mV. No current change can be seen with the addition of buffer solution at around 200s, show-
ing the specicity and ...
