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.
本公开利用刺激响应聚合物的聚集,通过磁泳从溶液中分离出诊断目标(如抗原)。诊断目标的分离为识别溶液中诊断目标的存在提供了途径。例如,利用双组分检测法(如夹心检测法),包括用刺激响应性聚合物功能化的磁性纳米粒子和附着在第二种刺激响应性聚合物上的捕获分子。
