Probing Supramolecular Structures in Solution Using Far-Zone Resonant Energy Transfer

Strategic Insights -

Research conducted at the University of Paris Saclay has shed new light on supramolecular structures in solution using an advanced X-ray spectroscopic technique called Far-Zone Resonant Energy Transfer (FZRET). This technique relies on the resonant energy transfer between donor and acceptor atoms, allowing researchers to probe the inhomogeneous distribution of ions in water. The study revealed the presence of nm-sized ionic clusters at a concentration of 4.1 M, providing valuable insights into the behavior of supramolecular structures.
