Multiplexed immunoassay based on micromotors and microscale tags

Abstract

This work reports on the coupling of antibody-functionalized micromotors and microwire-tagged proteins for rapid and multiplexed immunoassays. While micromotor-induced mixing accelerates the immunoreaction, tagging the proteins with microscopic particles of different sizes and shapes allows for their multiplexed discrimination, alerting of the presence of a biological threat.
