Here, we present a system in which self-propelled catalytic micromotors are biofunctionalized and trapped acting as an alternative concentrating mechanism. This system requires no external energy source, which facilitates integration and miniaturization.application/pdfenghttps://creativecommons.org/licenses/by-nc/3.0/620articlebioassaybiotinylationcatalysiscontrolled studyelectronicsenergy resourceimmobilizationlab on a chiplimit of detectionpriority journalself propelled micromotorchemical structuredevicesmicrofluidic analysisArticle
