Macromolecules in diverse phases can adsorb onto natural systems, composite materials, and thin-film devices. In a new report now published in Science Advances, Yuma Morimitsu and a research team in applied chemistry and polymer interfaces and molecular adhesion used atomic force microscopy (AFM) to visualize well-defined double-stranded DNAs and conducted molecular dynamics simulations to identify the adsorption mechanisms of polymer chains to solid surfaces.
