Optofluidic manipulation of Escherichia coli in a microfluidic channel using an abruptly tapered optical fiber

We report stable optical trapping and controlled manipulation of Escherichia coli cells in a microfluidic channel using an abruptly tapered optical fiber with 980-nm wavelength laser light launched. Stability of the trapping at different optical powers (10–70 mW) was demonstrated in fluids under different flow directions and velocities. The experimental results were supported by finite-element simulations and analytic calculations.
