Scientists have used DNA-linked nanoparticles to form a single-particle-thick layer on a liquid surface where the properties of the layer can be easily switched. Understanding the assembly of such nanostructured thin films provides a possible pathway to adjustable filters, surfaces with variable mechanical response, or even new ways to deliver genes for biomedical applications.
