Does rapid droplet generation increase the risk of cell damage?

2026-06-18

Answer:
Under standard operating conditions, rapid droplet generation does not significantly increase the risk of cell damage. 

 

The microfluidic channel diameter (approximately 60 μm) is larger than most mammalian cells, allowing cells to pass through without excessive mechanical stress. In addition, the hydrophobic surface properties of the channels reduce friction and minimize shear forces.

 

Although cells may transiently interact with barcoded beads during encapsulation, such interactions are brief and generally do not result in measurable damage. Overall, the impact of droplet generation on cell viability and transcriptomic integrity is minimal.
