In this first part of our online science exhibition, Rafa Carrascosa Marzo from Andrew Turberfield’s lab at Oxford University will exhibit some of his dynamic DNA structures.If you need a more though explanation of the exhibits below, please visit this post, where Rafa explains the pictures.
Computer model of the Rotaxane structure. The ring-shaped slider in the middle can be moved along the rail between the two stoppers at each end.
TEM images of Rotaxane structures. They measure 355 nm x 265 nm.
TEM images confirming that the Rotaxane structures are dynamic: The slider is moved from a central position in the rail (upper panel) to the left (lower panel).
