Development of a carbon paste electrode that is screen printed using a carbon/polymer mixture of suitable composition.
Notes:
- These electrodes can easily be chemically modified by the incorporation of reagents (electrocatalysts, redox mediators, complexation agents, enzymes, etc.) and by the attachment of micro- or nanoparticles to prepare electrochemical sensors for analytical applications. See for an example using rabbit anti-mouse immunoglobulin in an ELISA assay using a carbon ink electrode.
- Typical composition of a carbon ink expressed as mass fractions is graphite powder \(\pu{60\%}\) and polystyrene \(\pu{40\%}\).
