Digital Image Analysis for DETCHIP Code Determination.

DETECHIP is a molecular sensing array used for identification of a large variety of substances. Previous methodology for the analysis of DETECHIP used human vision to distinguish color changes induced by the presence of the analyte of interest. This paper describes several analysis techniques using digital images of DETECHIP.

Wild Plum: novel particles of improved optical brightness and fluorescence.

A novel compound named Wild Plum fluoresces blue, and has been synthesized to camouflage skin imperfections, addressing the market demand for an anti-aging product. Wild Plum imparts optical brightness and fluorescence and can be used as an ingredient in cosmetic formulations. Skin appearance before and after application of Wild Plum compounds demonstrated an improved appearance of skin including a decreased number of wrinkles.

DETECHIP: a sensor for drugs of abuse.

The design and preliminary characterization of a novel sensor for drugs of abuse, DETECHIP, is described in this proof-of-concept note. Combining both colorimetric and fluorimetric assays, DETECHIP is suitable for lab and field use. More than a conventional spot test which provides a single "yes or no" answer, DETECHIP provides twenty responses for a more complete characterization of suspect material.
