Micro-spot with integrated pillars (MSIP) for detection of dengue virus NS1.

In this paper, we demonstrate an extremely efficient technique of diagnosing dengue virus non-structural protein (NS1) using Micro-Spot with Integrated Pillars (MSIP). Detection using MSIP is performed by employing fluorescence immunoassay specific to dengue virus NS1. MSIPs are chemically modified to ensure efficient covalent binding of antibodies on the micropillars, whereas the enormous increase in the surface area (available for the reaction) induced by the micropillars amplifies the apparent rate, which enhances the signal intensity.
