Rotating Gold Nanomotors for High-Resolution Mapping of Subcellular Nanomotions. [PDF]

Small Methods
A nanomotor‐based method uses optically driven, rotating gold nanorods to detect nanometer‐scale cellular movements with 10 nm spatial and millisecond temporal resolution. Applied to live endothelial cells, the technique reveals subcellular mechanical activity and distinct frequency regimes, capturing transient, localized oscillations.
