Abstract: The present invention relates, in general terms, to nanoparticle solutions, kits, devices and methods of use thereof. The present invention is suitable for use in quantifying bacterial cells in a sample. The method of quantifying bacterial cells in a sample comprises passing the sample in a liquid form and an aqueous nanoparticle solution through a porous substrate such that the bacterial cells in the sample is trapped on the porous substrate and can be quantified by a colorimetric and/or fluorescence output emitted from the nanoparticle bound to the bacterial cells.

Abstract: A light emitting device, a method of fabricating a light emitting device and a method of controlling light emission. The light emitting device includes a plasmonic structure. The plasmonic structure is configured to have a plurality of localized surface plasmon resonances. The light emitting device also includes a broadband light emitting layer having an emission spectrum substantially overlapping wavelengths of the localized surface plasmon resonances. A spacer layer is disposed between the plasmonic structure and the broadband light emitting layer. A color of light emitted by the broadband light emitting layer is tunable by the localized surface plasmon resonances of the plasmonic structure.
