"a crossed two-layer scaffold routing"

English to French Tech/Engineering Biology (-tech,-chem,micro-) molecular machine

context
"a molecular machine comprising a movement part and a control part. The movement part comprises several machine elements which are adapted to be moved with respect to each other. These machine parts are molecular structures, particularly nanomolecular structures. The movement part includes a first molecular element (4), a second molecular element (5) and a linking element (6)."
"the first molecular element is a platform (4) and the second molecular element is a positioning arm (5). The positioning arm is fixed to the platform via the linking element (6)."
"The first molecular element and/or the second molecular element and/or the linking element preferably are biomolecules"
"the first molecular element is made from a crossed two-layer scaffold routing. A top layer is preferably rotated with respect to a bottom layer by an angle between 80° and 100°, particularly 90°."
"The square platform (first molecular element 4) consists of two layers of DNA double helices"
