Plasmon enhanced spectroscopy allows scientists to reach single molecule sensitivity and a lateral resolution even down to sub-molecular resolution. A major challenge for it to become a user-friendly analytical tool however is that scientists have lacked comprehension of most relevant experimental parameters with regard to the technology. Two researchers from Jena, Germany now present a method to unravel plasmonic properties during the experiment and thus provide a reliable approach to investigate and directly optimize experimental conditions.
