Carbon nanotubes reside at the boundary of condensed matter physics and polymer physics. Here we show that individual carbon nanotubes can be picked up and strained with micron-sized tweezers, allowing us to simultaneously study their optical, electronic, and vibrational properties. Experiments include recording the “sound” of a single nanotube vibrating due to thermal fluctuations and “seeing” its motion with light.
