Interleukin-6 Detection with a Plasmonic Chip

Abstract

Interleukin-6, a cytokine relating inflammatory and autoimmune activity, was detected with three fluorescence assays using a plasmonic chip. In their assays, the way of surface modification, sample volume, incubation time and mixing solution, were found to influence the detection sensitivity. When the assay was revised in the point of a rapid and easy process, the detection sensitivity was not compromised compared to assays with sufficient sample volume and assay time. To suit the purpose of immunosensing, the assay conditions should be determined.
