Abstract: Described herein are 1,2-dioxetanes that are useful as chemiluminescent probes, diagnostic agents, and imaging agents. Also described herein are compositions containing such compounds and methods of using the same.

Abstract: 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.

Abstract: 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.

Abstract: A method is presented for producing light using a liquid media. The method includes: suspending nanoparticles in a polar liquid media; disposing a pair of electrodes in direct contact with the liquid media; and generating an excitation signal between the electrodes in the pair of electrodes, thereby illuminating a portion of the nanoparticles.

Abstract: A compact apparatus for digital imaging of luminescent materials is provided. The apparatus can be readily transported by an individual and features a system of collapsible or foldable elements which allow it to be stored in a compact conliguration when not in use. The apparatus is contained within a case which when opened allows the apparatus to be placed into a use configuration by unfolding or otherwise extending the elements of the apparatus. The apparatus is useful for imaging a variety of materials and samples in life science applications.

Abstract: Acridans which are reactable with a peroxidase and peroxide. The acridans are characterized by having an aromatic leaving group ArO which is a di- or polyhalosubstituted phenoxy group. The compounds are useful in assays where one member of a binding pair is linked to the peroxidase and for detecting the peroxidase. The method can also be used to detect hydrogen peroxide.
