Development of a calcium biosensor based on lipid films on ZnO nanorods.Application to the analysis of bottled water

This thesis describes the development of a calcium solid mini sensor based on
lipid films on ZnO nanorods. The lipid film was composed from
dipalmitoylphosphatidylcholine (DPPC) and dipalmitoylphosphatidylcic acid
(DPPA). The calibration graph of EMF is logarithmically related to the
concentration of calcium ions in the range 10-6 to 10-3 M. The response times
of the electrode were less than 5 s. No memory effects were observed for this
electrode. The reproducibility of the electrode was less than 5%.The electrode
has shown good stability for a period of 1 month. The influence of a wide range
of metals and anions as potential interferences was checked. The method was
applied to the rapid detection of calcium ions in bottled waters.
