Characterization of liquid flows in microfluidic systems

Transient electro-osmotic flow of generalized Maxwell fluids in a straight pipe of circular cross section

“…With the development of microfluidic devices and their applications in microelectromechanical systems and microbiological sensors [1,2], the research field of electroosmosis (EO) has become very attractive. Recently, some researchers [3,4] pointed out that the micelle structure of polymer electrolyte membranes (PEMs) might consist of only cylindrical nano-channels, which facilitate water its associated total flux, as well as the protonic current, conductivity and water drag.…”

Fabrication of three-dimensional SU-8 microchannels by proton beam writing for microfluidics applications: Fluid flow characterisation

“…It was shown that microfluidic-based systems have a great potential in application for single-cell analysis [1,2] and instant analyses or so called point-of-care (POC) diagnostics [3][4][5]. In this respect, microfluidics systems provide conditions that are comparable to in vivo conditions [1].…”

“…Microchannel geometry and surface texture are considered as the crucial factors in determining fluid flow through microchannels. These factors mainly depend on microfabrication techniques and fabrication processes of the microchannels [2][3][4].…”

Transient electroosmotic flow of general Maxwell fluids through a slit microchannel

“…Microfluidics is one of the most important research areas in microelectromechanical systems (MEMS) due to its potential applications as a tool for studying fundamental physical and biochemical processes and a platform for performing chemical and biological assays [1,2]. Most solid surfaces acquire electrostatic charges when they are in contact with aqueous solution.…”
