Collaborators on the Confined DNA project have just published two works in Nano Letters and Macromolecules, journals of significant impact, among the best in their respective scientific fields.
- T. Vuletić and M. Lihter, along with Prof. Rađenović group, published a paper in Nanoletters journal (IF=12.9) on a novel method in production of nanopores: Electrochemical reaction in single layer MoS2: nanopores opened atom by atom. This approach confirms that facility-free nanopore preparation has an important technological potential. That is, electrochemical etching of nanopores may be performed as an atom-by-atom process, controlled by simple electrical measurement set-up, without advanced electron microscopes or other facilities. Our colleagues contributed by identifying and interpreting this nanoscale process from the electrical transport data. Paper (PDF)>>>

- The paper Polyelectrolyte Composite: Hyaluronic Acid Mixture with DNA was published in Macromolecules (IF=5.9), leading journal in the area of polymer science (Vuletić, Salamon, Delač Marion, Grgičin with S. Bernstorff from Elettra Syncrotrone). Our scientists gave a new outlook on the osmotic pressure of polyelectrolytes based on structural measurements (synchrotron X-ray scattering) and thus were able to determine the osmotic coefficient of DNA by comparing it with the coefficient of the hyaluronic acid (an electrically charged polysaccharide).
