Indian Scientists Develop Nanomaterial That Stimulates Brain Cells Without Surgery
In a groundbreaking discovery, researchers at the Institute of Nano Science and Technology (INST), Mohali, have pioneered a nanomaterial—graphitic carbon nitride (g-C₃N₄)—that can stimulate brain cells naturally, without electrodes, lasers, or magnets.
The study, published in ACS Applied Materials & Interfaces, shows that g-C₃N₄ enhances neuron growth, connectivity, and dopamine production while reducing toxic proteins linked to Parkinson’s disease in animal models. Unlike invasive treatments such as deep brain stimulation, the material generates tiny electric fields in response to natural brain signals, activating neurons and improving communication between them.
“This is the first demonstration of semiconducting nanomaterials directly modulating neurons without external stimulation,” said Dr. Manish Singh, lead researcher. He added that the innovation could transform therapies for Alzheimer’s, Parkinson’s, and brain injuries, while also advancing futuristic fields like bio-inspired computing using brain organoids.
While promising, the team emphasized the need for extensive preclinical and clinical trials before human applications.
