  • Instrument schematic for optical trapping force-detected absorption spectroscopy
  • Schematic for optical trapping force-detected absorption spectroscopy. A) The optically trapped probe particle is brought in vicinity of the sample. B) Optical excitation of the sample causes a force change at the probe. C) Brightfield microscope image of the experiment in progress. D) Comparison of optical trapping detected and bulk absorption spectra.
