FIG. 1.

Schematic of particle extraction mechanism. Upper right inset shows an optical microscope image of the microfluidic channel, while lower left inset shows the SEM image of the sub-microfiber with a defect decorated.

FIG. 2.

Longitudinal cross-section views of three-dimensional numerical simulations. (a) Optical field energy distribution of a target 3-μm PS particle trapped on the defect. (b) Velocity field around the target 3-μm PS particle. F s, F g, and F d represent scattering, gradient, and drag forces, respectively, acting on the PS particle. (c) Optical field energy distribution around the 700-nm diameter sub-microfiber.

FIG. 4.

(a)–(d) The deceleration of three PS particles in the trapping region at average fluid velocity v = 10 μm/s and laser power P = 0.4 mW. (e) The image of the trapping region on the microfluidic chip. (f) Two 3-μm PS particles aggregation were trapped on the 700-nm sub-microfiber with 700-nm PS particles dispersed around at P = 0.4 mW. (g) 3-μm PS particles began to accumulate at laser power P = 0.6 mW.

(a) Trapped particle percentage vs laser power at average fluid velocity v = 10 μm/s and FOM. (b) Trapped particle percentage vs fluid velocity at laser power P = 0.6 mW and its FOM.
