Abstract
Techniques for detection of virus-antibody nanocomplexes using a chip-based pillar array are provided. In one aspect, a method for virus detection is provided. The method includes the steps of: collecting a fluid sample from a virus-bearing source; contacting the fluid sample with an antibody that binds to viruses to form a sample-antibody mixture, wherein the antibody is labeled with a fluorescent tag; separating particles including any antibody-virus complexes, if present, from the sample-antibody mixture using an assay nanopillar array; and detecting the antibody-virus complexes, if present, in the particles from the separating step using fluorescence. A virus detection chip device and a chip-based immunoassay method are also provided.
