    • The invention provides a system for producing nanotubes, nanofibers and nanorods, the system comprising a wire array shaped as a cylinder such that the cylinder defines a void; a first furnace positioned within the void; a second furnace positioned opposite the first furnace to define a channel adapted to receive a portion of the cylinder as the cylinder rotates about its axis; a device for depositing spun fiber onto the wire array as the cylinder rotates; and a device for removing the deposited fiber from the array after the deposited fiber is heated within the channel. The invention also provides a method for producing nanotubes, the method comprising: supplying a cylindrical wire array, wherein the array defines an internal void; positioning a first furnace within the void; positioning a second furnace opposite the first furnace so as to define a channel between the first furnace and second furnace, the channel adapted to receive a portion of the cylindrical array as the array rotates about its axis; depositing spun fiber onto the array as the array rotates; heating the deposited fiber as it enters the channel; and removing the deposited fiber as it exits the channel.

    • Disclosed herein are methods and materials by which nanostructures such as carbon nanotubes, nanorods, etc. are bound to lectins and/or polysaccharides and prepared for administration to cells. Also disclosed are complexes comprising glycosylated nanostructures, which bind selectively to cells expressing glycosylated surface molecules recognized by the lectin. Exemplified is a complex comprising a carbon nanotube functionalized with a lipid-like alkane, linked to a polymer bearing repeated α-N-acetylgalactosamine sugar groups. This complex is shown to selectively adhere to the surface of living cells, without toxicity. In the exemplified embodiment, adherence is mediated by a multivalent lectin, which binds both to the cells and the α-N-acetylgalactosamine groups on the nanostructure.

    • An inflatable recreational device includes a first member and a plurality of second members, wherein the first member be a cylinder with an inner side and an outer side, and wherein the second members may be attached to the outer side thereof. The second members may form closed air chambers. A user may place him or herself within the first member for protection during use of the device. In another embodiment, a plurality of second members may form a cavity, without needing a first member, to protect the user.
