High‐Throughput Inertial Focusing of Micrometer‐ and Sub‐Micrometer‐Sized Particles Separation
The ability to study individual bacteria or subcellular organelles using inertial microfluidics is still nascent. This is due, in no small part, to the significant challenges associated with concentrating and separating specific sizes of micrometer and sub-micrometer bioparticles in a microfluidic format. In this study, using a rigid polymeric microfluidic network with optimized microchannel ge...
متن کاملDeterministic microfluidic ratchet.
We present a deterministic, nonthermal ratchet where the trajectory of particles in a certain size range is not reversible when the sign of the pressure gradient is reversed at a low Reynolds number. This effect is produced by employing triangular rather than the conventional circular posts in an array that selectively displaces particles transported through the array. The ratchet irreversibly ...
متن کاملAdvanced Transport Models for Sub-Micrometer Devices
To overcome limitations of the classic drift-diffusion model, several higher-order transport models such as Stratton’s energy-balance model and Bløtekjær’s hydrodynamic model have been proposed. While for the drift-diffusion model the only transport parameter to be modeled correctly is the carrier mobility, there are many more significant parameters in higher-order models which cannot be direct...
متن کاملDeterministic particle transport in a ratchet flow.
This study is motivated by the issue of the pumping of particle through a periodic modulated channel. We focus on a simplified deterministic model of small inertia particles within the Stokes flow framework that we call "ratchet flow." A path-following method is employed in the parameter space in order to retrace the scenario which from bounded periodic solutions leads to particle transport. De...
متن کاملOrganic Fluorescent Nanofibers and Sub-micrometer Rods
Luminescent nanofibers are a particular class of nanofibers. Like the other members of this family, they are very small objects whose typical diameters range between 50 to 500 nm (it is noteworthy that beyond these values, the term of microfibers is more appropriate) and lengths can reach several hundred micrometers. Besides, they display special photophysical behavior. By definition, fluoresce...
