Abstract
A miniaturized,
disposable, and low cost Ag/AgCl pseudoreference
electrode based on inkjet printing has been developed. Silver ink
was printed and chlorinated with bleach solution. The reference electrodes
obtained in this work showed good reproducibility and stability during
at least 30 min continuous measurement and even after 30 days storage
without special care. Moreover, the strategy used in this work can
be useful for large scale production of a solid-state Ag/AgCl pseudoreference
electrode with different designs and sizes, facilitating the coupling
with different electrical/electrochemical microsensors and biosensors
