    摘要： An ultra sensitive method for detection of biomolecules includes the step of providing a plurality of bioreceptor functionalized nanoparticle probes. The nanoparticles can include metal, semiconductor, radioactive isotope or fluorescent dye molecules. A sample solution suspected of including the target is contacted with the probes, wherein if present, the target binds to the bioreceptor. After such binding a separating step follows. In the separating step, probes having the target bound thereto are separated from probes not having the target bound thereto. In one embodiment probes having the target bound thereto are then decomposed to generate ions, or broken into discrete radioactive isotopes or fluorescent dye molecules to form a solution including a large plurality of metal ions, radioactive isotopes or dye molecules. A concentration of ions, radioactive isotopes, or dye molecules in the solution is then determined and using this information the concentration of the target in the original sample solution is determined.

    摘要： A metal nanoparticle supported on or dispersed in a polymer is irradiated with photons from a laser source to address the nanoparticles. The polymer is transmissive to the photons and addressed nanoparticles transform the energy of the photon to heat which is transferred to a material in the vicinity of the nanoparticle. The locally heated material undergoes a physical or chemical transformation upon heating. The transformed material can be a material in the proximity of the metal nanoparticle supported polymer or metal nanoparticle/polymer composite. In this manner thermally induced physical or chemical transformations can be carried out in very small volumes of material without significant heating to the bulk of the material.

    摘要： A method of forming carbon nanotube-polymer composites includes the steps of forming a mixture solution including a plurality of carbon nanotubes dispersed in a co-solvent. The co-solvent includes an organic solvent and a second solvent being a short chain fluorinated carboxylic acid having a boiling point below 150° C. which is less oxidizing than nitric acid, and is soluble in both the organic solvent and water. The first polymer is mixed with the mixture solution to form a polymer including mixture. The co-solvent is removed from the polymer mixture to form a dispersed nanotube-polymer composite. The second solvent can be trifluoroacetic acid.
