Electrokinetic flow is an efficient means to manipulate liquids and samples in lab‐on‐a‐chip
devices. It has a number of significant advantages over conventional pressure‐driven flow …

The Joule heating (JH) is a ubiquitous phenomenon in electrokinetic flow due to the
presence of electrical potential gradient and electrical current. JH may become pronounced …

Delineating its usage in separation, purification and detection processes across a variety of
disciplines, from industry to applied research, this work discusses the principles, techniques …

We present an experimental study of temperature gradient focusing (TGF) exploiting an
inherent Joule heating phenomenon. A simple variable-width PDMS device delivers rapid …

IEF 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 …

A simple microfabrication technique for the preparation of a tapered microchannel for
thermally generated pH gradient isoelectric focusing (IEF) has been demonstrated. The …

Equilibrium gradient techniques constitute a class of separation methods that combine the
steps of separation and concentration by using a gradient in one or more counteracting …

A microchannel device is presented which separates and focuses charged proteins based
on electric field gradient focusing. Separation is achieved by setting a constant …

A method for the whole chip temperature measurement is developed and presented here.
This method includes two major contributions:(i) a specially developed measurement model …
