Water quality test based on dielectrophoretic measurements of fresh water algae Selenastrum capricornutum

open access: yesJ. Environ. Monit., 2003
A method is described whereby dielectrophoresis of algal cells is used to perform rapid water quality analysis, specifically detecting the presence of CuSO4. The dielectric collection spectrum of the fresh water alga Selenastrum capricornutum was determined for a range of concentrations of CuSO4 from 25 mg L(-1) to 0.25 mg L(-1) for exposure times of ...
