Overall strategy for the MP-enhanced detection of MCP-1. Comparison between the use of magnetic actuation to pull beads to the sensor surface and passive bead diffusion The inset shows representative real time shifts in microring resonance accompanying bead binding in both a magnetically-actuated and passive diffusion detection experiment.
