Tuning Deterministic Lateral Displacement Devices Using Dielectrophoresis
Fig. S1 Layout of the D-DLD with peripheral vacuum pump and electronic connections. (a) The device is fabricated in PDMS and glass using replica molding. (b) Micrographs of the entrance channels and a side-wall. (c) A scale drawing of the separation device. A stream of particles injected into the device is continuously separated about the critical diameter, D c. Particles smaller than the criti...
متن کاملImproved performance of deterministic lateral displacement arrays with triangular posts
Deterministic lateral displacement arrays have shown great promise for size-based particle analysis and purification in medicine and biology. Here, we demonstrate that the use of an array of triangular rather than circular posts significantly enhances the performance of these devices by reducing clogging, lowering hydrostatic pressure requirements, and increasing the range of displacement chara...
متن کاملMultidirectional sorting modes in deterministic lateral displacement devices.
Deterministic lateral displacement (DLD) devices separate micrometer-scale particles in solution based on their size using a laminar microfluidic flow in an array of obstacles. We investigate array geometries with rational row-shift fractions in DLD devices by use of a simple model including both advection and diffusion. Our model predicts multidirectional sorting modes that could be experiment...
متن کاملSeparation of deformable particles in deterministic lateral displacement devices.
Using numerical simulations, we study the separation of deformable bodies, such as capsules, vesicles, and cells, in deterministic lateral displacement devices, also known as bump arrays. These arrays comprise regular rows of obstacles such as micropillars whose arrangements are shifted between adjacent rows by a fixed amount. We show that, in addition to the zigzag and laterally displaced traj...
متن کاملFractionation by shape in deterministic lateral displacement microfluidic devices
The ability to use microfluidic systems to fractionate a mixture of suspended particles based on their shape could lead to important applications. In the case of bioparticles, for example, shape is an important factor used to identify and characterize them. In fact, cell morphology has long been used in clinical diagnosis and it is also a marker of cell cycle (Sugaya et al. 2011; Beech et al. 2...
