The present disclosure utilizes the aggregation of stimuli-responsive polymers to isolate a diagnostic target (e.g., an antigen) from a solution using magnetophoresis. Isolating the diagnostic target provides a route to identify the presence of the diagnostic target in the solution. For example, utilized is a two-component assay (eg sandwich assay) comprising a magnetic nanoparticle functionalized with a stimuli-responsive polymer, and a capture molecule attached to a second stimuli-responsive polymer.
