Abstract
The present invention relates to methods for detecting polymeric analytes, especially biopolymers, and sensors for detecting the polymeric analytes. The present invention uses magnetic beads in a rotating magnetic field to provide a visual detection of the presence of a polymeric analyte, such as nucleic acids, lipids, polysaccharides, proteins, etc. When a polymeric analyte binds to the magnetic beads, application of a rotating magnetic field to the beads results in unique pinwheel formations. Without the presence of the polymeric analyte, the movement of the magnetic beads induced by the rotating magnetic field differs significantly from the pinwheel formations. The pinwheel, therefore, is used to detect the presence of polymeric analytes.
