Abstract: Devices, compositions, and methods are described which provide a tubular nanostructure or a composite tubular nanostructure targeted to a lipid bilayer membrane. The tubular nanostructure includes a hydrophobic surface region flanked by two hydrophilic surface regions. The tubular nanostructure is configured to interact with a lipid bilayer membrane and form a pore in the lipid bilayer membrane. The tubular nanostructure may be targeted by including at least one ligand configured to bind to one or more cognates on the lipid bilayer membrane of a target cell.

Abstract: Devices, compositions, and methods are described which provide a tubular nanostructure targeted to a lipid bilayer membrane. The targeted tubular nanostructure can have a surface region configured to pass through a lipid bilayer membrane of a cell, a hydrophobic surface region flanked by two hydrophilic surface regions configured to form a pore in a lipid bilayer membrane of a cellular organelle, and at least one ligand configured to bind one or more cognates on the lipid bilayer membrane of the cellular organelle. The target cell can be, for example, a tumor cell, an infected cell, or a diseased cell in a subject. The tubular nanostructure can form a pore in the lipid bilayer membrane of the cellular organelle, e.g., mitochondria, which can permit transit or translocation of at least one compound across the membrane and cause cell death of the target cell.
