Abstract [en]

In this chapter we present sensors based on ZnO nanostructures suitable for sensing in small volumes and can be used for intracellular as well as extracellular environments. The principle of the measurement is based on the potentiometric effect. The measurement electrodes were constructed by growing ZnO nanostructures on the tip of sub-micrometer glass pipettes and were used versus Ag/AgCl reference electrodes. By functionalizing the ZnO nanostructures based electrodes, the selectivity of the sensors can be tuned to detect the ion or the analyte in question. The developed sensors were used to measure the concentration of most of the common ions like calcium, potassium, sodium and magnesium. In addition different biological analytes were also measured. These include glucose, urine, uric acid and cholesterol. The developed sensors showed good sensitivity and a wide dynamic range and represent a step towards developing efficient sensor of interest for human health diagnostic.
