Abstract: (3444 Views)
A fluorescent glucose biosensor based on the grown ZnO nanorods on printed circuit boards (PCBs) has been fabricated. The ZnO nanorods have been grown on the conductive PCBs using hydrothermal method. The seed layer has been spin coated on PCBs. New annealing temperatures and durations have been utilized in fabricating the proposed fluorescent glucose biosensor. XRD pattern and SEM image show that ZnO nanorods have been formed in the desired form during the growth process. The biosensor output is based on the photo luminescence (PL) spectra. After essential treatments of the sensor, 1 mM to 80 mM glucose concentrations have been drop casted on the PCBs and their PL response were measured. The results show the high sensitivity of the fabricated sensor to the glucose concentration variations. The amount of the change in PL spectra for different glucose concentrations has been quantified and discussed.
