Abstract
The present invention provides a method for preparing catalytic particles and using them for increased sensitivity in lateral flow immunoassays. Palladium salt is reduced in the presence of a protein using sodium borohydride as a reducing agent to form brown or gray particles. These particles catalytically develop a dye to detect the presence of an analyte.
