Printed artificial neurons from MoS₂ successfully trigger firing in living mouse brain cells
By
David Brzostowicki
Summary
Researchers at Northwestern University have successfully printed artificial neurons from molybdenum disulfide (MoS₂) on flexible plastic that produce spiking waveforms closely matching biological action potentials. In experiments with living Purkinje cells in mouse cerebellar tissue, these artificial spikes drove real brain cells to fire — marking the first demonstration that a printed device can produce electrical signals that biological neurons accept and respond to. Published in Nature Nanotechnology, this breakthrough could pave the way for a new generation of neural interfaces and implants.

An array of artificial neurons printed on a flexible wafer produce spiking waveforms closely matching biological action — and drive living mouse brain cells to fire.
The result, recently published in Nature Nanotechnology, could lay groundwork for a new generation of neural interfaces.
