摘要
Novel silica nanoparticle/CdTe quantum dot (QD) composite probes were prepared and used as reporters in fluorescent lateral flow test strips. When alpha-fetoprotein (AFP) was used as a model analyte, the results indicated that the fluorescent test strips were at least 10 times more sensitive than conventional gold-based test strips.
