Relationship between Hydrophobic Beads Attachment and Fluid Flow in PDMS Microchannel
The hydrophobic beads as mimic of the living cell attachment to microchannel in fluid flow were observed and analyzed. Beads were collided to the microchannel wall by the right angle flow. We found that beads attachment in the fluid flow should be decided by the fluid velocity to the wall, and hydrophobic interaction between the channel and beads. Shear force is less effective in this case
