This paper presents an inertial microfluidic device with a simple serpentine micro-channel to continuously separate particles with high performance. Separation of micro/nano-particles has a variety of potential applications in biomedicine and industry. Among the existing separation technologies, a label-free technique without the use of antibody affinity,(More)
This review reports the progress on the recent development of micromixers. The review first presents the different micromixer types and designs. Micromixers in this review are categorized as passive micromixers and active micromixers. Due to the simple fabrication technology and the easy implementation in a complex microfluidic system, passive micromixers(More)
In this letter, the authors report a system for magnetic manipulation of ferrofluid droplets and their dynamic behavior. The magnetic field was generated by an array of planar coils, which were fabricated on a double-sided printed circuit board ͑PCB͒. The permanent magnetic moment of the ferrofluid droplet was created by the field of a pair of permanent(More)
Magnetic actuation has emerged as a useful tool for manipulating particles, droplets and biological samples in microfluidics. A planar coil is one of the suitable candidates for magnetic actuation and has the potential to be integrated in digital microfluidic devices. A simple model of microcoils is needed to optimize their use in actuation applications.(More)
Despite significant advancements over the years, there remains an urgent need for low cost diagnostic approaches that allow for rapid, reliable and sensitive detection of malaria parasites in clinical samples. Our previous work has shown that magnetic resonance relaxometry (MRR) is a potentially highly sensitive tool for malaria diagnosis. A key challenge(More)
— This paper reports a novel optofluidic sensor for measuring dynamic interfacial tensions. The field of micro optofluidics utilizes both microfluidic and microoptic technologies. Thus, our sensor consists of a mirofluidic network and an optical detection system. The sensor is able to measure both surface tension or liquid/liquid interfacial tension. In the(More)
It is my pleasure to assume the role of the Editor-in-Chief of Micromachines from March 2016. The journal was founded in 2009 by Prof. Miko Elwenspoek from the University of Twente, and published its first issue in 2010. Twenty years ago, I spent 6 months as a visiting PhD student in Prof. Elwenspoek's research group of Transducers Science and Technology,(More)
