Scientists Unveil Innovative Technique for Manipulating Nanoscale Diamond Sensors
Gemstones may not be every girl's best friend, but diamonds, especially the nanoscale ones, could one day revolutionize our understanding of brain function, thanks to recent advancements in research at MIT and other institutions.
Researchers at MIT's Quantum Engineering Group, along with collaborators, have developed a novel method to control these nanoscale diamond sensors. Capable of measuring minute magnetic fields, these sensors could provide insights into the dynamics of neuron communication in the brain, and also aid in precise analysis of novel materials, such as superlenses and "invisibility cloaks."
Nitrogen-vacancy (N-V) centers, natural defects inside diamonds, serve as the basis for these quantum sensors. Sensitive to external magnetic fields like compasses, the presence of these defects gives diamonds their unique hues. A team led by Paola Cappellaro, Esther and Harold Edgerton Associate Professor of Nuclear Science and Engineering at MIT, has developed a technique to control these sensors.
To achieve this, they first targeted the sensors with green laser light, detecting red light emissions that indicated the location of N-V centers. Applying a microwave field to the nanoscale sensor manipulates the electron spin of the defect, altering the intensity of light emissions. By using various microwave pulse sequences, the researchers efficiently collected information about external magnetic fields and used signal-processing techniques to interpret this data, eventually reconstructing the entire dynamic magnetic field.
Using a three-millimeter square diamond sample as the sensor, the researchers demonstrated this technique’s effectiveness in accurately reconstructing the magnetic field. Despite its size, smaller, tens-of-nanometers-wide sensors can also be utilized. Diamonds' carbon-based composition makes them safe for injection into living cells, and potential applications include growing neurons on the sensor to monitor the magnetic fields they produce and transmit to other nerves noninvasively.
While the team's work doesn't directly involve MIT in the development of nanoscale diamond sensors, other research at the university has explored gravity through optical levers and other quantum-related topics. The discoveries in quantum sensing technologies can have profound implications for understanding brain function and potentially treating brain disorders.
