Abstract

Surface plasmons are recognized as one of the most sensitive probes for measuring refractive index on a sensing surface and intensively applied to detection of bio-related objects. We have also shown that a localized surface plasmon sensor is able to detect influenza viruses reacting to monoclonal antibodies fixed on the sensing surface [1]. As a next step of our development, we fabricate sensing channels to detect multiple subtypes of the virus from one measurement. Since the size of surface plasmon localization is ~200 nm, the localized surface plasmons potentially enable parallel detection of multiple analytes from a sample with ultra-small volume. In this presentation, we propose a method to fabricate the sensing channels, and discuss the process of the fabrication.
