Microscopic devices activates Neurons to modulate Brain cells activity

Magnetic fields generated by microscopic devices implanted into the brain may be able to modulate brain-cell activity and reduce symptoms of several neurological disorders. Micromagnetic stimulation appears to generate the kind of neural activity currently elicited with electrical impulses for deep brain stimulation (DBS) – a therapy that can reduce symptoms of Parkinson’s disease, other movement disorders, multiple sclerosis and chronic pain – and should avoid several common problems associated with DBS, report Massachusetts General Hospital investigators.

Nanotube Technology to reduce the cost of Medical Diagnostics

Researchers at Oregon State University have tapped into the extraordinary power of carbon “nanotubes” to increase the speed of biological sensors, a technology that might one day allow a doctor to routinely perform lab tests in minutes, speeding diagnosis and treatment while reducing costs.

The new findings have almost tripled the speed of prototype nano-biosensors, and should find applications not only in medicine but in toxicology, environmental monitoring, new drug development and other fields.

The research was just reported in Lab on a Chip, a professional journal. More refinements are necessary before the systems are ready for commercial production, scientists say, but they hold great potential.

SMART DUST:

Smartdust is a hypothetical system of many tiny microelectromechanical systems (MEMS) such as sensors, robots, or other devices, that can detect, for example, light, temperature, vibration, magnetism or chemicals; are usually networked wirelessly; and are distributed over some area to perform tasks, usually sensing.
