摘要：
Highly charged nanoparticles of a conjugated polyelectrolyte brush were used to sense the human alpha-fetoprotein (AFP) by observing selective superquenching in several minutes. The unique property of nanoparticles that the self-aggregation causes an unchanged or enhanced fluorescence can reduce the interference from non-target substance significantly.
