  • Remote nanoscale photochemistry using guided emission in nanowires
    Patent number: 8674328
    Abstract: A method of fabricating a nanodevice includes providing a nanowire having a first portion and a second portion. The nanowire has a polymer coating. A nanostructure is provided that is proximate to the second portion of the nanowire. Solely the first portion of the nanowire is irradiated with near-infrared radiation, thereby exciting the first portion to generate ultraviolet radiation. The generated ultraviolet radiation is guided from the first portion along the nanowire toward the second portion, so that a region of the polymer coating on the second portion is polymerized and bonds the nanostructure to the nanowire.

  • Method for Polymer Coating and Functionalization of Metal Nanorods
    Publication number: 20110183140
    Abstract: The present invention relates to polymers and their use in coating metal nanorods (especially gold nanorods), and to the coated nanorods compositions. In particular, the invention relates to a process for forming cetyltrimethylammonium bromide (CTAB)-coated gold nanorods and to such coated nanorods that additionally comprise an external cross-linked polymer coating.
