Title: Innovations of John Figueras in Analytical Chemistry
Introduction
John Figueras is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of analytical chemistry, particularly in the detection of nitrogen-containing compounds. With a total of 6 patents to his name, Figueras has developed innovative methods and compositions that enhance the accuracy and efficiency of chemical analysis.
Latest Patents
Among his latest patents, Figueras has introduced a method for detecting nitrogen-containing compounds capable of releasing ammonia upon enzymatic action. This method involves contacting a sample suspected of containing such a compound with a novel assay composition that includes at least one enzyme. The enzyme catalyzes the decomposition of the compound to ammonia, which is then detected by its reaction with a diketone, resulting in a measurable color or fluorescence. This assay composition can be integrated into single-layer or multilayer analytical elements, enhancing the reliability of the detection process.
Another significant patent focuses on reducing detectable species migration in analytical elements. This invention features a radiation-transmissive, detectable species migration-inhibiting layer positioned between a porous radiation-blocking layer and a radiation-transmissive reagent layer. This configuration allows for the effective analysis of liquids while minimizing the migration of detectable species, such as dyes, which can interfere with accurate measurements.
