Hydrodynamic trapping
Webabstract = "It is known that obstacles can hydrodynamically trap bacteria and synthetic microswimmers in orbits, where the trapping time heavily depends on the swimmer flow field and noise is needed to escape the trap. Here, we use experiments and simulations to investigate the trapping of microrollers by obstacles. Web28 mrt. 2016 · Hydrodynamic trapping offers an attractive method for particle manipulation in free solution without the need for optical, electric, acoustic, or magnetic fields. Here, we develop and demonstrate the Stokes trap, which is a new method for trapping multiple particles using only fluid flow.

Web3 apr. 2024 · The tunable PDMS membrane was then integrated with a single-cell trapping structure to investigate single-cell deformation under a series of squeezing conditions. The layout of the microfluidic chip is shown in Fig. 4(a). Single-cell trapping was realized by the hydrodynamic principle. 34 34. WebWe find that hydrodynamic trapping can significantly amplify (by ≈40%) the nutrient exposure of bacteria, both chemotactic and non-chemotactic. The subtle interactions between hydrodynamic and chemotactic effects reveal non-trivial variations in this “hydrodynamic amplification,” as a function of relevant biophysical parameters.
Web1 sep. 2024 · Hydrodynamic trapping configurations exist in almost all geological settings, in uplifted basins, in ancient platform bulges, in large deltas and their frontal areas … Web21 jan. 2011 · Overall, the hydrodynamic trap is a new platform for confinement, micromanipulation, and observation of particles without surface immobilization and eliminates the need for potentially perturbative optical, magnetic, and electric fields in the free-solution trapping of small particles.

Web17 feb. 2024 · Calculating hw A critical step in mapping hydrodynamic traps in a target formation is making a water isopotential map (step 3 above). Before that can be done, however, one must calculate a potentiometric value for each well. Calculate H w for each well using the formula where: Z = structural elevation of target formation Web29 okt. 2012 · The hydrodynamic theory is triggered by the fact that water in many hydrocarbon bearing formations is in regional motion or flow conditions. Under this hydrodynamic condition, hydrocarbon trapping may behave markedly both in position and in attitude (i.e. tilted) from those under hydrostatic conditions (Hubbert, 1967).
