MINIGRAPH project completes: graphene brain implant guided by magnetic robot

A European consortium has completed the four-year, nearly €4 million MINIGRAPH project. It produced the first preclinically validated system combining ultra-thin graphene neural probes with magnetic robotic guidance that reaches deep brain targets along curved trajectories conventional rigid stereotactic frames cannot navigate.

• Graphene probes about 10 µm thick show ~200x higher charge injection capacity than platinum-iridium
• Accelerated ageing tests project more than 10 years of implant stability
• Magnetic navigation steers flexible probes along curved paths with sub-millimeter accuracy
• Selected from over 400 proposals under EIC Pathfinder, grant Nº 101070865
