Biofunctionalized self-propelled micromotors as an alternative on-chip concentrating system
2014, Restrepo-PĂ©rez, Laura, Meyer, Anne K., Helbig, Linda, Sanchez, Samuel, Schmidt, Oliver G.
Sample pre-concentration is crucial to achieve high sensitivity and low detection limits in lab-on-a-chip devices. 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.
