Additively Manufactured Electrochemical and Biosensors

The present chapter describes biosensor device properties and electro analytical methods involved in the development of environmentally sustainable hybrid polymers doped with silver nanowires (Ag NW) nano graphite, conductive polymer composites, graphene, nonporous metals, and carbon nanotubes for the biosensor’s applications. The hybrid polymers doped with Ag NW showed bio compatibility, neutral adhesion and the formulated ink was used for the strain responsive biosensors. The nano graphite incorporated for the redox electrodes which are further used for the effective detection of Pb (II) and Cd (II) elements. However, electrochemical performances of conductive polymers showed decrease in the peak current with increase in the electrode potential leading to water ingress and used for the application of additive manufacturing (AM) where water is in contact with the AM process. The electrochemical biosensors used with graphene, carbon nanotubes and porous metals in presence of biomarkers with their challenges in the AM process discussed in detail.
