| الوصف: | Magnetic artificial cilia (MAC) are small actuators inspired by biological cilia found in nature. In microfluidic chips, MAC can generate flow and remove microparticles, with applications in anti-fouling. However, the MAC used for anti-fouling in the current literature has dimensions of several hundred micrometers in length, which limits the application to relatively large length scales. Here, biologically-sized magnetic artificial cilia (b-MAC) which are only 45 micrometers long and that are randomly distributed on the surface, are used to remove microparticles. It is shown that microparticles with sizes ranging from 5 to 40 µm can be removed efficiently and the final cleanness ranges from 69% to 100%, with the highest cleanness for the highest actuation frequency applied (40 Hz). The lowest cleanness is obtained for microparticles with a size equal to the average pitch between the b-MAC. The randomness in cilia distribution appears to have a positive effect on cleanliness, compared with the authors’ earlier work using a regular cilia array. The demonstrated self-cleaning by the b-MAC constitutes an essential step toward efficient self-cleaning surfaces for real-life application in miniaturized microfluidic devices, such as lab-on-a-chip or organ-on-a-chip devices, as well as for preventing fouling of submerged surfaces such as marine sensors. |
