Multielectrode arrays restoration using 3D printing technologies

Advances in science and technology are rapidly applied in everyday practice when their use becomes cost-effective. In this study, we demonstrated the potential of using filament 3D printing technologies for repairing multielectrode arrays (MEAs), a key yet expensive component of most in vitro bioelectronic devices. This paper presents a method for restoring the functionality of MEAs after the failure of their reference electrodes by replacing them with special attachments made of 3D plastic and platinum strip. The obtained results allow for an extension of the life cycle of MEAs, making the use of bioelectronic technologies more accessible for solving actual problems in medicine and biology.
