Researchers have developed a novel method to stimulate and mature human brain organoids using graphene, a one-atom-thick sheet of carbon. Key study findings include that regular use of GraMOS helped brain organoids form stronger connections, better organized networks, and more advanced communication between neurons – even in models made from Alzheimer’s patients. Graphene did not harm neurons or organoid structure, even over long periods, proving safe and biocompatible.

Enhanced disease modeling was achieved as early-stage Alzheimer’s organoids revealed functional differences in network connectivity and excitability when stimulated. Furthermore, graphene-stimulated organoids were linked to a simple robot in a closed feedback loop, enabling it to respond to visual cues. This advancement accelerates neural maturation, allowing disease progression to be studied earlier and in a more physiologically relevant context, which could improve drug testing timelines and offer new insights into how diseases like Alzheimer’s alter brain circuitry.

"Our technology bridges a critical gap in organoid research," said Alex Savchenko, Ph.D., co-senior author and chief executive officer of Nanotools Bioscience. "It offers a reliable, repeatable way to activate neurons, which can transform both fundamental neuroscience and translational studies."
