Abstract

We report fabrication and performances of a new immunoassay device, which integrates a novel nanoplasmonic sensor array inside a microfluidic channel. The new assay has demonstrated 106 fold detection limit enhancement of a model direct Protein A immunoassay over glass reference (from 2nM to 850 aM, i.e. 120 ng/ml to 50 fg/ml) and 6 fold of incubation time reduction (2 hours to 20 min) compared to conventional 96-well plate immunoassay.
