Au nanoparticle- and silver-enhancement reaction-amplified microgravimetric biosensor

An ultrasensitive microgravimetric biosensor has been developed incorporating Au nanoparticle-amplified sandwiched immunoassay and silver enhancement reaction; Au nanoparticle-promoted silver(I) reduction and silver metal deposition result in ca. two orders of magnitude improvement in human IgG quantification.
