We examine the effect of Dean number on inertial focusing spherical particles suspended in flow through curved microfluidic ducts. Previous modelling particle migration ducts assumed rate was small enough that a leading-order approximation background with respect to produces reasonable model. Herein, we extend our model situations involving moderate (in microfluidics context) while Reynolds rem...

Soft lithography has provided a low-expertise route toward micro/nanofabrication and is playing an important role in microfluidics, ranging from simple channel fabrication to the creation of micropatterns onto a surface or within a microfluidic channel. In this review, the materials, methods, and applications of soft lithography for microfluidics are briefly summarized with a particular emphasi...

Machine vision is widely used in an industrial environment today. It can perform various tasks, such as inspecting and controlling production processes, that may require humanlike intelligence. The importance of imaging technology for biological research or medical diagnosis is greater than ever. For example, fluorescent reporter imaging enables scientists to study the dynamics of gene networks...

Microfluidics gained prominence with the application of microelectromechanical systems (MEMS) to chemistry and biology in an attempt to benefit from the miniaturization of devices for handling of minute fluid samples under precisely controlled conditions. The field of microfluidics exploits the differences between microand macro-scale flows, for example, the absence of turbulence, electro-osmot...

We report three novel demonstrations: 1. Coplanar electrowetting 2. Electrowetting on a printed circuit board (PCB) and 3. Transport and mixing in an “open” microfluidic substrate. Similar to “soft” lithography which enabled many researchers to easily prototype and experiment with continuous-flow microfluidics, this work allows researchers to easily experiment with discrete-flow microfluidics (...

Microfluidics is considered an important technology that is suitable for numerous biomedical applications, including cancer diagnosis, metastasis, drug delivery, and tissue engineering. Although microfluidics is still considered to be a new approach in urological research, several pioneering studies have been reported in recent years. In this paper, we reviewed urological research works using m...

Parameter identification techniques are particularly attractive to determine the inertial parameters of robot manipulators and manipulated payloads. These parameters are particularly needed in implementation of a model-based controller for robot manipulators. In this paper, the inertial parameters of a manipulated rigid-body object have been estimated. The Newton-Euler equations will be employe...

Open-surface digital microfluidics refers to droplet manipulations in an open surface. Different chemical/biological reaction protocols can easily be demonstrated in the same device by reprogramming the order of droplet manipulations. While continuous-flow or liquid-plug microfluidics within microchannels have inherently limited programmability, there is no limit of reprogrammability in open-su...

This study presents a novel microfluidic approach for developing large scale screening assays of anticancer compounds on 3D multicellular spheroids. We have developed a microfluidic device with associated protocols that combine the high-throughput characteristics of droplet microfluidics for spheroid formation and aggregation with those of single-phase microfluidics for substance exchange, long...

Microfluidic chips provide unparalleled control over droplets and jets, which have advanced all natural sciences. However, microfluidic applications could be vastly expanded by increasing the per-channel throughput and directly exploiting the output of chips for rapid additive manufacturing. We unlock these features with in-air microfluidics, a new chip-free platform to manipulate microscale li...
