Abstract

Hydrodynamic tweezers provide strong, adjustable fluid forces that trap single cells without surface contact or cell modification. We show that trapping arrays can be created under continuous net flow needed for delivery of nutrients and reagents in dynamic measurements. We quantify the competition between net flow and trapping, and we find that traps withstand net flow velocities up to 1 cm/sec. Traps can be arbitrarily numbered-up to create arrays that capture cells from a flowing fluid stream. This trapping approach provides a promising tool for parallel dynamic measurement of many individual cells in a controlled chemical environment.
