摘要： The present invention provides organically modified silica (ORMOSIL) nanoparticles into which have been incorporated two-photon absorption dye molecules. The two photon absorption dye displays a unique aggregation induced fluorescence enhancement behavior. As a result ORMOSIL nanoparticles with high amounts of the dye can be prepared. These particles can be used for imaging. In one embodiment, the nanoparticles can additionally have incorporated therein a photosensitizer. The photosensitzer can be activated by intraparticle fluorescence resonance energy transfer (FRET) from the dye aggregates resulting in enhanced fluorescence and singlet oxygen generation from photosensitizer under two-photon excitation conditions. Such nanoparticles can be used for photodynamic therapy applications.

摘要： A method is provided for detection of analytes using the Surface Plasmon Resonance effect. The method comprises providing a metal film on a transparent substrate. The free surface of the metal film is exposed to a test sample. An anlyte in the sample can interact directly with the metal film or via analyte binding molecules (ABMs) complexed to the film. Light is directed incident to the surface of film in contact with the substrate. Light is reflected from the surface of the film under SPR conditions. The reflected light is collected and the second and/or third harmonics of the resulting electrical signal, which are indicative of the phase and polarization state of the reflected light, are determined. The second and third harmonics are correlated to the presence and/or concentration of the analyte.

摘要： Provided are methods and compositions for inhibiting expression of one or more target genes. The compositions contain RNA polynucleotides that can inhibit expression of a target gene via RNA interference (RNAi) electrostatically complexed with surface functionalized gold nanorods (GNRs). The RNA polynucleotides are not covalently bound to the surface functionalized GNRs. The method involves inhibiting expression of a target gene in an individual. The method is performed by administering to the individual an effective amount of a composition containing surface functionalized GNRs electrostatically complexed with RNA polynucleotides, such as siRNA, that can inhibit expression of the target gene via RNAi. The siRNA is not covalently bound to the surface functionalized GNRs.
