Abstract: Pore-forming peptides or proteins modified utilizing DNA nanotechnology, which provides definition and control of pore size, an increase in stability when inserted in a lipid membrane, and membrane affinity. Chemical modifications are easily made on the compound through hybridization to the oligonucleotide attached to the peptide or protein. The compound can hybridize to a DNA template thereby defining the number of monomers assembled to a pore and thus the size of the formed pore. The DNA template can range from a unique single strand composed of multiple hybridization sites separated by flexible linkers to a complex rigid DNA nanoconstruct, such as a DNA origami-based ring, serving as a scaffold for pore formation. Hydrophilic modification at the transmembrane segment or terminus of the peptide provides long-lived pores and keeps the compound in a membrane-spanning conformation.

Abstract: A molecular machine comprising a movement part (2) including a first molecular element (4), a second molecular element (5), and a linking element (6) for constraining a relative movement of the first molecular element (4) and the second molecular element (5), and a control part configured to generate an electrical field around the movement part (2), wherein the first molecular element (4) is fixed relative to the control part, wherein the second molecular element (5) is movable relative to the first molecular element (4) in at least one degree of freedom, and wherein the second molecular element (5) is electrically charged such that the second molecular element (5) aligns to said electrical field.
