Thermal diffusivity measured using a single plasmonic nanoparticle.
A method to measure thermal diffusivity around a single heated gold nanoparticle is presented. It is based on photothermal single particle microscopy and employs the phase delay of temperature modulation due to finite thermal diffusivity. The phase delay is detected optically averaging over the focal volume of a diffraction limited beam of light. Thermal diffusivity is extracted by comparison t...
متن کاملSingle Nanoparticle Plasmonic Sensors
The adoption of plasmonic nanomaterials in optical sensors, coupled with the advances in detection techniques, has opened the way for biosensing with single plasmonic particles. Single nanoparticle sensors offer the potential to analyse biochemical interactions at a single-molecule level, thereby allowing us to capture even more information than ensemble measurements. We introduce the concepts ...
متن کاملPhotoluminescence of a single complex plasmonic nanoparticle
We report detailed investigations of the photoluminescence (PL) generated from an individual gold nanoflower, a highly branched plasmonic nanoparticle. Compared to nanostructures with simple shapes, such as spheres, nanorods, and bipyramids, nanoflowers exhibit more distinct features, i.e., the PL spectra and far-field emission patterns are strongly dependent on the wavelength and polarization ...
متن کاملMeasurement of Scattering Nonlinearities from a Single Plasmonic Nanoparticle.
Plasmonics, which are based on the collective oscillation of electrons due to light excitation, involve strongly enhanced local electric fields and thus have potential applications in nonlinear optics, which requires extraordinary optical intensity. One of the most studied nonlinearities in plasmonics is nonlinear absorption, including saturation and reverse saturation behaviors. Although scatt...
متن کاملReusable plasmonic aptasensors: using a single nanoparticle to establish a calibration curve and to detect analytes.
We demonstrate plasmonic aptasensors that allow a single nanoparticle (NP) to generate a calibration curve and to detect analytes. The proposed reusable aptasensors have significant advantages over conventional single-NP based assays in terms of sensitivity and reproducibility.
