Single molecules don't absorb much light, making detection difficult to begin with. An even bigger problem, however, is that light-induced heating in the sample and in the microscope tip can produce so much noise that the signal is lost.

An even bigger problem, however, is that light-induced heating in the sample and in the microscope tip can produce so much noise that the signal is lost.

This new measurement method combines the chemical selectivity of optical absorption spectroscopy with the atomic-scale resolution of scanning tunneling microscopy. The method literally feels how a molecule changes shape when it absorbs energy.

Single molecule absorption spectroscopy is an extremely sensitive technique for analytical chemistry, for measuring electrical properties of molecules, and for studying energy transfer on surfaces. While most molecules don't fluoresce -- limiting the usefulness of single molecule fluorescence spectroscopy -- all molecules absorb, making single molecule absorption spectroscopy a much more general approach.
