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.

Catalytic particles for signal enhancement for lateral flow immunoassays

A method for dry graphene transfer comprising growing graphene on a growth substrate, chemically modifying a transfer substrate to enhance its adhesion to graphene, contacting the graphene on the growth substrate with the transfer substrate and transfer printing; and separating the transfer substrate with attached graphene from the growth substrate. The growth substrate may be copper foil. The transfer substrate may be a polymer, such as polystyrene or polyethylene, or an inorganic substrate.
