Method Atomic force microscopy
Comments Using the sensitivity of an atomic force microscope to probe cellular nanomechanics in an acoustically insulated environment,Pelling et al. demonstrated that the cell wall of single, living cells of Saccharomyces cerevisiae exhibited local periodic nanoscale motions of similar average amplitude (3.0±0.5nm), yet variable, temperature-dependent frequencies (0.9–1.6 kHz)
