Disclosed herein is a composition for ultrasensitive bioassay applications. The composition includes a plurality of dispersible, nanoparticles having a size less than 500 nm. The nanoparticles contain a metal catalyst or a metal catalyst precursor. The nanoparticles are conjugated to at least one biospecific binding reactant that is selectively reactive with a target analyte. The composition includes a dispersing medium. A method and a kit for conducting bioassays are described.

Catalytic marking nanoparticles for ultrasensitive bioassay applications

The invention relates to ultrasensitive bioanalytical assays based on the use of high-gain catalytic chemical amplification methods. The ultrasensitive bioanalytical assays of the invention utilize high gain catalytic chemical amplification methods to detect the presence and to quantify the concentrations of target analytes labeled with specific binding reagents or biomarkers comprising a catalyst or a catalyst precursor.

Ultrasensitive bioanalytical assays based on the use of high-gain catalytic chemical amplification

A thermally imageable element can be imaged using heat alone without the need for photosensitivity or post-imaging processing. The element contains image-forming chemistry that comprises i) image precursor chemistry and ii) a catalyst or a catalyst precursor that upon imagewise heating is capable of promoting thermally induced image formation with the image precursor chemistry. The image-forming chemistry i) and ii) components are in reactive association and uniformly dispersed or dissolved within a binder in one or more layers of the element. Thus, the element is capable of being thermally addressed to provide a visible image as a result of thermally induced catalytic transformation of the image-forming chemistry.

Thermographic imaging elements and processes for their use

Photothermographic imaging materials having increased photospeed are provided by certain selenium chemical sensitizers that are added during the formulation of a photothermographic emulsion. These selenium chemical sensitizers can be used alone or in combination with other sulfur, tellurium, or gold chemical sensitizers as well as with oxidatively decomposed sulfur-containing compounds.
