摘要：
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.
