Nanoparticles have the potential to revolutionize the way we think about imaging. A new study has revealed that using nanoparticles in combination with laser frequency modulation can provide unprecedented resolution and accuracy in imaging. The study, published in the journal Nature Photonics, describes how the team of scientists from the Institute of Photonics and Quantum Sciences at Heriot-Watt University used a nanoscale particle to accurately detect the frequency of a laser beam. This process allowed them to map the laser’s frequency across a sample with a resolution of 1/10th of a nanometer. This level of resolution is more than 10 times higher than that achievable with traditional imaging techniques. The study demonstrates the potential of nanoparticles for imaging with unprecedented accuracy and resolution, and could open the door to a new era of imaging technology.
