Researchers Create New Nanosensors of Force

Jan 1, 2025 by News Staff

The newly-developed all-optical nanosensors are luminescent nanocrystals that can change intensity and/or color when you push or pull on them; they are...

Tang et al. discovered neutronic molecules, in which neutrons can be made to cling to quantum dots, held just by the strong force: the red item represents a bound neutron, the sphere is a hydride nanoparticle, and the yellow field represents a neutron wavefunction.
