The Nature Nanotechnology study, published on 15 April, was led by Northwestern University's Mark Hersam using printable inks containing molybdenum disulfide and graphene on flexible polymer substrates.
Tests on mouse brain slices showed biological neurons fired in step with the printed devices, suggesting signals could be decoded like natural tissue and supporting neuromorphic computing and future brain-computer interfaces.
Researchers say the technology could improve AI energy efficiency and eventually aid prosthetics or damaged brain function, but experts caution long-term communication with living neurons and full circuit integration remain unresolved.
