Design and operation principle of the microfluidics-based Marangoni surfer. (a) The motion of the microfluidics-based Marangoni surfer is generated by the surface tension gradient induced by the surfactant release. A remotely actuated soft magnetic pump enables the controlled release of the surfactant....
Towards their inner side, the enclosures have machined pockets for inclusion of optical sensor spots (optodes) for oxygen sensing (Fig. 1b; Supplementary Fig. 1c) and perforations, which allow the bolting of the device together (Fig. 1b; Supplementary Fig. 1a). To delineate the individual ...
