We review the state of the art in microfluidic separation technique based two-phase laminar flow with an application focus on chemical and biological sample. As we describe herein, two-phase laminar flow in the microfluidic extraction has several biological and engineering advantages over other methods including high reproducibility, biocompatibility, and selectivity. We review advances in applications of two-phase laminar flow and examine key parameters such as flow rate, phase composition, and surface charge property, how these can affect extract performance with the technology including microfluidic separation system. A special technology focus is given to emerging novel integrative microfluidic extraction, which aims to merge aqueous phase laminar flow and electric field technologies into simple packages. We conclude with a brief discussion of some of the emerging challenges in the field and some of the approaches that are likely to enhance their application.

“…Maruyama et al [71] reported on a contactor in which a discontinuous ridge was formed between contacting channels. Images show that curved liquid-liquid interfaces form at the openings, and rates for a metal ion extraction were observed to be elevated above those for an open interface device of similar geometry.…”

“…In microfluidics systems, segmented/slug flow and stratified flow are the most commonly used flow patterns for liquid extraction in micro reactors. In stratified flow extraction, stability for contacting is achieved by surface treatment or structured walls (Tokeshi et al 2002;Maruyama et al 2004). The liquid phases can be separated at the output using separator or Y junction outlet with a hydrophobic and a hydrophilic branch (Aljbour et al 2010;Sato et al 2003).…”
