New “all-optical” nanoscale force sensor accesses previously inaccessible environments
Illustration of atomic arrangement within a single lanthanide-doped nanocrystal. Each lanthanide ion can emit light. Credit: Andrew Mueller/Columbia Engineering Mechanical forces are an essential feature of many physical and biological processes. Telemetry of mechanical signals with high sensitivity and spatial resolution is required for a wide range of applications, from robotics to cell biophysics and medicine, and even space travel.…
