  • Gold nanorod/polymer nanocomposites and sensors based thereon
    Patent number: 9897547
    Abstract: A nanocomposite structure includes: a) a charged fibrous substrate including fibers having disposed on their surfaces a multilayer structure including a layer of a first polyelectrolyte and disposed thereon a layer of a second polyelectrolyte of opposite charge from the first, the second polyelectrolyte forming the outermost layer of the charged fibrous substrate; and b) charged nanorods having a charge opposite that of the charged fibrous substrate, including gold nanorods each having disposed on its surface one or more layers, the outermost of which is a third polyelectrolyte having a charge opposite that of the second polyelectrolyte, wherein the first and third polyelectrolytes may be the same or different; wherein the charged nanorods are disposed unaligned with respect to each other on the charged fibrous substrate.
