Enhancing Electrochemical Biosensors with Electroactive Polymers

  1. Molecules that recognize analytes are known a bioreceptors. Examples of bioreceptors include: DNA, antibodies, enzymes or even cells. This part of the process is called bio-recognition which involves signal generation interacting with bioreceptors and analytes
  2. After that, the transducer helps convert one form of energy to another, therefore converting bio-recognition event into a measurable signal. This is known as signalisation.
  3. Next, the electronic section of the biosensors processes the transducer signal and prepares it for display (last step). Electronic performs signal conditioning such as amplification, then are quantified for display.
  4. Lastly, all these signals are converted and shown through a display (normally, in a numerical form) to show the concentration of an analyte. The output signal could be shown in graphics, images, numbers are more.
  • Oxidation: loss of electrons during a reaction involving increasing amounts of oxygen levels
  • Reduction: gain of electrons due to the decrease in oxygen levels (opposite of oxidation)
