Abstract: An Ink-based digital printing system comprises an external fluid applicator for applying multi-component, multi-functional fountain solution to a surface of an imaging plate. The plate is image wise exposed using a high power laser to remove primary components of the fountain solution from select regions of the plate according to digital image data, leaving a layer of the secondary components at said select regions. The plate is then inked with ink useful in printing. The ink adheres to the select regions from which the primary components have been removed to form an ink image. The ink image is transferred at an image transfer step wherein the secondary components enable efficient transfer of the ink to a medium with reduced image quality defects. The multi-component fountain solution comprises primary components that reject or repel ink, and secondary components that function as a release agent.

Abstract: A colorimetric reagent in the form of nanoparticles, composite nanoparticles, and nanoparticle coatings, including methods of use, methods of preparation, deposition, and assembly of related devices and specific applications. The colorimetric reagent comprises cerium oxide nanoparticles which are used in solution or immobilized on a solid support, either alone or in conjunction with oxidase enzymes, to form an active colorimetric component that reacts with an analyte to form a colored complex. The rate of color change and the intensity of the color are proportional to the amount of analyte present in the sample. Also described is the use of ceria and doped ceria nanoparticles as an oxygen storage/delivery vehicle for oxidase enzymes and applications in biocatalytic processes in anaerobic conditions of interest in biomedicine and bioanalysis.
