Sub-nanometre resolution in single-molecule photoluminescence imaging
Through the use of a plasmon-active atomically sharp tip and an ultrathin insulating film, and precise junction control in a highly confined nanocavity plasmon field at the scanning tunnelling microscope junction, sub-nanometre-resolved single-molecule near-field photoluminescence imaging with a spatial resolution down to ∼8 Å is achieved.

Room-temperature ultrafast nonlinear spectroscopy of a single molecule
Frequency-resolved transient excited-state absorption of a single molecule is measured at room temperature. The dynamic Stokes shift and vibrational cooling are directly measured with 25 fs temporal resolution and a spectral detection bandwidth of hundreds of meV.

Single-molecule light absorption
It has long been thought that the detection of individual molecules in ambient conditions via their absorption signature was out of reach. Now, three independent research groups have developed three different methods that allow such a feat.
