A tour de force: Engineers discover new 'all-optical' nanoscale sensors of force
Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These ‘all-optical’ nanosensors are probed with light only and therefore allow for fully remote read-outs — no wires or connections are needed.
