Trapping of big particles by the rapidly fabricated microtrap array.

(a–c) A 10.0 μm SiO2 particle was captured by the microtraps. (d–f) A 5.0 μm SiO2 particle can easily pass the traps. (g–i) A 3.0 μm SiO2 particle can also easily pass the traps. (j) The photography of the microdevice. (k,l) Percentages of the microparticles for different sizes before and after the microtrap array. Scale bars are 30 μm.
