The expression of potential molecular candidates for chloride ion channels in primary human granulocytes and granulocytic cell lines
INTRODUCTION AND HYPOTHESIS: The project aims to identify potential candidates for chloride (Cl-) ion channels in granulocytes, and granulocytic cell lines. It is hypothesised that Cl- ion channels, in particular hBest1, are implicated in the role of granulocytes in response to inflammation. …

Synthesis and Characterization of Miniaturized Fluorescence Sensors for Aqueous and Cellular Measurements
… first was to develop lipobead-based sensors for chloride. The halide-specific fluorescence dye, lucigenin, was immobilized into the phospholipid membrane of the lipobeads to enable chloride ion detection. The fluorescence intensity of lucigenin decreases with increasing chloride ion concentration …

Determination of chloride diffusion constants for concretes of differing water to cement ratios and admixtures
Reinforced concrete exposed to chlorides is subject to rapid deterioration once the concentration of the chloride ion in the concrete reaches a critical level to cause corrosion of the reinforcing steel. The chloride ion diffuses through concrete according to Fick's Law, which is a function of …
