Immunoassays: Dielectrophoresis-Based Protein Enrichment for a Highly Sensitive Immunoassay Using Ag/SiO2 Nanorod Arrays (Small 12/2018)

In article number 1703265, Junxue Fu and co-workers fabricate a dielectrophoresis (DEP) device integrated with versatile nanorod arrays for highly effective and rapid protein enrichment and detection. First, target antigen proteins are concentrated to an antibody binding region, then the immunoassays are performed, and consequently the detection signal is greatly enhanced while the incubation time required for signal saturation is notably reduced due to the enrichment of biomarkers.
