Abstract: Methods of transferring nanostructures from a first substrate to another substrate using a copolymer polymerized from one or more non-crosslinking monomers and one or more comonomers bearing crosslinkable groups as a transfer medium are provided. Relative to a poly(methyl methacrylate) homopolymer, the crosslinkable copolymers bond more strongly to the first substrate and, as a result, are able to transfer even very narrow nanostructures between substrates with high transfer yields.

Abstract: Methods of sorting carbon nanotubes and methods of forming films of aligned carbon nanotubes using rod-coil copolymers are provided. The rod-coil copolymers have a tri-block or di-block architecture and include a conjugated polymer segment (“rod” segment) that binds the copolymer to the carbon nanotubes via pi-pi interactions and a non-conjugated polymer segment (“coil” segment) that aids with the sorting and dispersion of the carbon nanotubes in solution and/or controls the spacing of the carbon nanotubes in films made therefrom.

Abstract: Random copolymers, crosslinked thin films of the random copolymers and cell culture substrates comprising the crosslinked thin films are provided. Also provided are methods of making and using the copolymers, thin films and substrates. The copolymers are polymerized from glycidyl methacrylate monomers and vinyl azlactone monomers. The crosslinked thin films are substrate independent, in that they need not be covalently bound to a substrate to form a stable film on the substrate surface.
