Microfluidic systems have been extensively studied in recent years as potential alternatives for problematic conventional methods of sperm selection. However, despite the widespread use simple straight channels these systems, impact channel geometry on selected quality has not thoroughly investigated. To explore this further, we designed and fabricated serpentine microchannels with different radii curvature, inspired by tortuous structure cervix. Our results showed that presence gentle...
Abstract Separation of particles or cells has various applications in biotechnology, pharmaceutical and chemical industry. Inertial cell separation, particular, been gaining a great attention the recent years since it exhibited label‐free, high‐throughput efficient performance. In this work, first, an inertial contraction–expansion array microchannel device, capable passively separating two with diameters 4 10 μm, was numerically studied. Then, validated model combined curved geometries...
Particle cross-stream migration in electrohydrodynamic microfluidic systems exhibits intriguing behaviors, which makes it interesting when viewed from a fundamental perspective and promising for nanoparticle focusing separation applications. So far, particle behavior such has been explained with the slip-induced lift force model (Saffman model), predicts central or side based on direction of electric field fluid flow. However, our previous work, we observed patterns that did not adhere to...
Resistive pulse sensing (RPS) has proved to be a viable method for the detection and characterization of micro nano particles. Modern fabrication methods have introduced different nanopore geometries resistive sensors. In this paper, we numerically studied effects membrane thickness pore's cone angle, as main geometrical parameters, on performance nanopores used nanoparticle in method. To compare performance, three quality parameters were investigated - sensitivity, duration amplitude. The...
The isolation of extracellular vesicles (EVs) from milk, a complex mixture colloidal structures having comparable size to EVs, is challenging. Although ultracentrifugation (UC) has been widely used for EV isolation, this significant limitations, including long processing time at high g-force conditions and large sample volume requirements. We introduced new approach based on nature nanoentities cellulose nanofibers (CNFs) short low centrifugation isolate EVs various milk fractions. flexible...
The lateral migration of colloidal particles inside a microfluidic channel has gained attention due to being both fundamentally intriguing and applicable for particle separation, such as cancer cell isolation or extracellular vesicle purification. Applying an external electric field combined with pressure-driven flow induces migrations. In this study, new modes have been found by experimentally investigating 6 µm in the co-presence flow. experiments revealed importance relative strengths...
