Enhancing Electrochemical Biosensors with Electroactive Polymers

  1. 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.
  2. 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.
  3. 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.
  • Reduction: gain of electrons due to the decrease in oxygen levels (opposite of oxidation)

Binding a Antibody to a CP Substrate

Antibody-Recognition: It’s kinda self explanatory, but this method specifically uses antibody/antigen biorecognition interactions. One main plus point to this method is, that the target analyte (‘antigen’), does not need to be purified prior to detection. There are several steps in a biosensor, one of which involves purification. This step is known as PCR purification — the removal of enzymes, nucleotides, primer, and other unnecessary components that don’t bind well. Some analytes that could be detected using this method includes proteins, and cytokines.
