Abstract: The present invention provides a detachable carrier support member for bicycle cargo racks includes a base plate, a frame rack set, and a plurality of clamping block sets. The base plate is fixedly joined to the bottom of a carrier, wherein the bottom of the base plate is attached to the frame rack set. Further, the base plate is secured on a fixed position by the plurality of clamping block sets that clamps and holds on to the support bar of the bicycle cargo rack. To attach the carrier support member to the bicycle cargo rack, the plurality of clamping block sets is inserted into a wedging groove disposed at two lateral frame racks of the frame rack set; whereby two control shafts brake and allow the user to quickly secure the carrier to and remove the carrier from the cargo rack.

Abstract: The present invention generally relates to nanotechnology and, in particular, to wireframe nanostructures which may be formed from nucleic acids. In various aspects, the invention relates to molecular structures having a plurality of vertices and pathways connecting the vertices, which may be formed from nucleic acids, including bundles or tubes of nucleic acids. Such molecular structures may form shapes such as icosahedrons, octahedrons, tetrahedrons, or other polyhedra, which may define an interior space. The interior space may be used, for example, to contain a molecule for further study, or to contain a molecule for drug delivery purposes. In some cases, the molecular structure may be stabilized using relatively short nucleic acid strands that interact with two or more nucleic acid portions within the structure, thereby substantially immobilizing the portions relative to each other.
