"Revealing the Mysteries of Aromatic Molecules' Bond with Gold"
Scientists from the Hefei Institutes of Physical Science, Chinese Academy of Sciences, have used Surface-enhanced Raman Spectroscopy (SERS) to observe the interactions between aromatic molecules and gold surfaces at the single molecular level. By constructing an Au nanodimer structure with a subnanometer gap, they obtained surface molecular vibration spectrum information and achieved highly sensitive SERS detection of polycyclic aromatic hydrocarbons (PAHs). This research provides new insights into the interfacial interaction between aromatic molecules and gold, with implications for both fundamental science and technological applications.
