AbstractIEF is one of the most powerful and prevalent techniques used in separation sciences. The power of IEF comes from the fact that it not only separates analytes based on their pI but also focuses them into highly resolved bands. In line with the miniaturization trend spurring the analytical community, the past decade has yielded a wealth of ...

Microfluidic ion-sensing devices
Analytica Chimica Acta, 2008Quantitative determinations of ions in a variety of media have been performed traditionally via one of three approaches: optical instrumental methods (e.g., atomic absorption, and inductively-coupled plasma-optical emission or mass spectrometry), "wet" methods, or ion-selective sensors.

Bioanalysis in microfluidic devices
Journal of Chromatography A, 2002Microfabricated bioanalytical devices (also referred to as laboratory-on-a-chip or micro-TAS) offer highly efficient platforms for simultaneous analysis of a large number of biologically important molecules, possessing great potential for genome, proteome and metabolome studies.

Polyimide-based microfluidic devices
Lab on a Chip, 2001This paper describes the development of polyimide-based microfluidic devices. A layer transfer and lamination technique is used to fabricate flexible microfluidic channels in various shapes and with a wide range of dimensions. High bond strengths can be achieved by cure cycle adaptation and surface treatment of the polyimide layers prior to bonding ...

Integrated microfluidic devices
Analytica Chimica Acta, 2004“With the fundamentals of microscale flow and species transport well developed, the recent trend in microfluidics has been to work towards the development of integrated devices which incorporate multiple fluidic, electronic and mechanical components or chemical processes onto a single chip sized substrate.

Electrochemical paper‐based microfluidic devices
ELECTROPHORESIS, 2015Self‐pumping porous microfluidic devices have attracted significant interest because of their low cost and broad applicability in point‐of‐care and low resource settings. One limitation of many of the devices is sensitivity and selectivity for detection.

Micromagnetic–microfluidic blood cleansing device
Lab on a Chip, 2009Sepsis is a lethal disease caused by a systemic microbial infection that spreads via the bloodstream to overwhelm the body's defenses. Current therapeutic approaches are often suboptimal, in part, because they do not fully eliminate the pathogen, and hence the source of deadly toxins.

Microfluidic Control Using Colloidal Devices
Science, 2002By manipulating colloidal microspheres within customized channels, we have created micrometer-scale fluid pumps and particulate valves. We describe two positive-displacement designs, a gear and a peristaltic pump, both of which are about the size of a human red blood cell. Two colloidal valve designs are also demonstrated, one actuated and one passive,
