A method is presented for storage and on-demand release of nanoparticles. Nanoparticles produced by this method can be dried and stored for an extended period of time and subsequently released on-demand in a solvent of choice to form stable suspensions without the need for additional surfactants or stabilizers and without any loss in functionality or material properties. This method can be used to store various categories of nanomaterials including metals, metal oxides, metal chalcogenides, magnetic, polymeric and semiconductor nanoparticles.

Method for storing and releasing nanoparticles

A method is presented for synthesizing particles in the presence of a solid phase. Of note, sorption is used to associate a precursor(s) for synthesizing the particles onto or into the surface of a host structure prior to the chemical reaction that results in the particles being formed in or on surface of the host structure. Particles produced by this method can be stored for long durations and released on-demand in a solvent of choice to form stable suspensions without the need for any additional surfactants or stabilizers.

The present invention provides fluorescent dyes that are based on firefly luciferin structure. These dyes are optimally excited at shorter wavelengths and have Stokes shift of at least 50 nm. The fluorescent dyes of the invention are useful for preparation of dye-conjugates, which can be used in detection of an analyte in a sample.
