Electromechanics on the Nanometer Scale: Emerging Phenomena, Devices, and Applications

Nava Setter

Coupling between electrical and mechanical phenomena is ubiquitous in nature and underpins the functionality of materials and systems as diversified as ferroelectrics and multiferroics to electroactive molecules to biological systems. Recent years have wit ...

Manipulation of magnetic microparticles in liquid phases for on-chip biomedical analysis methods

Ulrike Lehmann

Magnetic microparticles and their application in bioanalytical microfluidic systems have been steadily gaining interest in recent years. This progress is fueled by the comparatively large and long range magnetic forces that can be obtained independently of ...

Piezoresistivity and tunneling-percolation transport in apparently nonuniversal systems

Peter Ryser, Claudio Grimaldi, Niklaus Johner

We formulate a generalized tunneling-percolation model that describes the electrical properties of conductor-insulator cellular disordered systems. This model predicts and explains the experimentally observed universal and nonuniversal behaviors of such pr ...

Two-Dimensional Magnetic Droplet Manipulation Platform for Miniaturized Bioanalytical Applications

Martinus Adela Maria Gijs, Virendra Kumar Parashar, Caroline Vandevyver, Ulrike Lehmann

We present a new approach for the manipulation of small liquid samples for the miniaturization of bioanalytical systems. In our system, minute liquid volumes are manipulated via the interaction of a changeable magnetic field and magnetic microparticles con ...

Noise and small-signal modeling of nanoscale MOSFETs

Ananda Sankar Roy

After years of intensive research effort, the design of RF integrated circuits in CMOS has now reached a wide acceptance for industrial designs. This is due to the high unity gain frequency and low-noise performance of today's deep sub micrometer MOS trans ...

Droplet-Based DNA Purification in a Magnetic Lab-on-a-Chip

Martinus Adela Maria Gijs, Virendra Kumar Parashar, Caroline Vandevyver, Ulrike Lehmann

Merge, Mix, Split and Transport, these are the main manipulation steps used for on-chip droplet-based DNA purification (see figure). The system is able to extract genomic material from dilute cell samples by using the actuation of magnetic microparticles w ...
