Laser-Induced forward Transfer of Highly sensitive and Versatile Microelectrodes Arrays for the interfacing of electrogenic cells – LIFT-MEA

The aim of this interdisciplinary project is to adapt advanced laser technologies for applications in the field of life electronics and health.
The complexity of certain organs constitutes, for biologists, a major obstacle to deciphering their functioning and better understanding certain pathologies. In this context, the use of simplified in vitro biological models is therefore a promising avenue of study to try to improve our understanding.
For electrogenic cells (neuronal networks, cardiomyocytes, muscle cells, etc.), these studies require high-resolution recording tools to study and understand their functioning and the use of multi-site recording devices such as microelectrode arrays (MEAs) are valuable tools.
In this context, the emergence of 3D printing techniques and their recent use for the fabrication of chemical and biological sensors seems to be a major asset to further develop MEA technology and provide new innovative solutions.
The objective of our project is to take advantage of the many benefits of the laser-assisted deposition technique (LIFT) for the fabrication of low-cost, high-sensitivity and fully versatile multi-electrode arrays (MEAs).
Its realisation will ensure easier access to MEA technology coupled with almost unlimited design versatility to address many biological questions.
