A paper-based colorimetric assay for the determination of bilirubin has been developed. The method is based on the in-situ reduction of chloroauric acid to form gold nanoparticles. A chromatographic paper was patterned using a wax printer. Chloroauric acid was drop-cast onto the reagent zone. In the presence of bilirubin, gold(III) ions are …
The gold ions were directly reduced to gold atoms by the sodium citrate, and many of the gold atoms immediately accumulated into colloidal gold solution.

gold, referred to as flour, flood, or colloidal gold, is lost in processing. Early miners recovered no more than 60% of as-sayed gold values, and as late as 1945 recovery of free gold averaged only 70-75% (Spiller, 1983). Moreover, it is likely that most remaining placer deposits have a higher percentage
