Background:

  • Flow injection analysis (FIA) systems offer automation, reproducibility, and small sample volumes.
  • Biosensors provide selective and sensitive analyte detection.
  • Microdialysis and FIA systems are sophisticated tools when integrated with biosensors.

Purpose of the Study:

  • To describe a miniaturized microdialysis flow-through system for glucose determination.
  • To focus on amperometric immunosensors for detecting environmental contaminants and proteins.
  • To explore microbial sensors for monitoring water pollutants.

Main Methods:

  • Development of a miniaturized microdialysis flow-through system.
  • Utilisation of amperometric immunosensors with antibodies for analyte detection.
