Symmetry-protected Micromanipulations

Page

By embedding symmetry in a 3D microfluidic geometry (e.g., octahedral symmetry shown in the following figure), we realized distinct microfluidic functions classified by subgroups of these symmetries. These functions include a strain-free flow in 3D, which can be used for trap-free manipulations of...
