Objectives

  1. To develop a novel robust on-line membrane based toxicity sensor.
  2. To design and optimise Pt microelectrodes on a silicon wafer.
  3. To electrodeposit minute amounts of metallic mercury on these microelectrodes.
  4. To deposit phospholipid layers on the Hg/Pt electrode microelectrode(s) .
  5. To test and calibrate the system in the laboratory as to its ability to detect classes of biomembrane active toxic compounds.
