Abstract One of the vital functions of naturally occurring cilia is fluid transport. Introduction Achieving fluid transport at the microscale is particularly difficult owing to the lack of inertial effects 1 , 2. Methods Fabrication We employ surface micromachining techniques involving a simple two-mask lithographic process.
Setup and experimental protocol of pumping experiments To study the fluid pumped by the cilia, we incorporated an array of cilia inside a microchannel loop. Full size image. Results and discussion The soft magnetic cilia get magnetized in the presence of an external magnetic field and tend to align along the direction of the field. All arrays have four rows of cilia with 25 cilia per row. Conclusions We demonstrate fluid pumping by an array of beating magnetic cilia. References 1. Article Google Scholar 3.

Scientific Reports [15 Mar , 8 1 ]. Type: Research Support, Non-U. Abstract The zebrafish sperm activation profoundly depends upon the homogeneous mixing of the sperm cells with its diluent in a quick succession as it alters the cell's extracellular medium and initiates their motility. Manual stirring, the traditional method for zebrafish sperm activation is tedious, time-consuming, and has a poor outcome. In this aspect, an artificial cilia embedded serpentine microfluidic is designed through which hydrodynamic factors of the microfluidic environment can be precisely regulated to harness uniform mixing, hence ensuring a superior sperm activation.
