Abstract
In this chapter, we present a hybrid microsystem that combines magnetic actuation with in situ optical detection. The chosen detection mechanism allows the observation and measurement of single magnetic microparticles of different sizes, as well as the detection of fluorescent labels attached to the particles' surface. We are able to detect mouse IgG as target antigen in a sandwich immunoassay down to a concentration of 0.1∈ng/ml. Our work represents a first step toward a full diagnostic LOC system for detection of specific antigens. © Springer Science+Business Media LLC 2009.
