  • Control of Molecular Motor Motility in Electrical Devices
    Control of Molecular Motor Motility in Electrical Devices Thesis submitted in accordance with the requirements of The University of Liverpool for the degree of Doctor in Philosophy By Laurence Charles Ramsey Department of Electrical Engineering & Electronics April 2014 i Abstract In the last decade there has been increased interest in the study of molecular motors. Motor proteins in particular have gained a large following due to their high efficiency of force generation and the ability to incorporate the motors into linear device designs. Much of the recent research centres on using these protein systems to transport cargo around the surface of a device. The studies carried out in this thesis aim to investigate the use of molecular motors in lab- on-a-chip devices. Two distinct motor protein systems are used to show the viability of utilising these nanoscale machines as a highly specific and controllable method of transporting molecules around the surface of a lab-on-a-chip device. Improved reaction kinetics and increased detection sensitivity are just two advantages that could be achieved if a motor protein system could be incorporated and appropriately controlled within a device such as an immunoassay or microarray technologies. The first study focuses on the motor protein system Kinesin. This highly processive motor is able to propel microtubules across a surface and has shown promise as an in vitro nanoscale transport system. A novel device design is presented where the motility of microtubules is controlled using the combination of a structured surface and a thermoresponsive polymer. Both topographic confinement of the motility and the creation of localised ‘gates’ are used to show a method for the control and guidance of microtubules.

To overcome this problem, we have developed a non-electrolytic micro/nano electroporation (NEME) electrode surface, in which the metal electrodes are coated with a dielectric. A COMSOL based numerical scheme was used to simultaneously calculate the excitation frequency and dielectric material properties dependent electric feld delivered across the dielectric, fuid fow, electroporation feld and Clausius-Mossotti factor for yeast and E. coli cells fowing in a channel fow across a NEME surface. A two-layer model for yeast and a three-layer model for E. coli was used. The numerical analysis shows that in NEME electroporation, the electric felds could induce electroporation and dielectrophoresis simultaneously. The simultaneous occurrence of electroporation and dielectrophoresis gives rise to several interesting phenomena. For example, we found that a certain frequency exists for which an intact yeast cell is drawn to the NEME electrode, and once electroporated, the yeast cell is pushed back in the bulk fuid.

ABSTRACT Electrophoresis is one of the widely used techniques in molecular biochemistry, microbiology, biomedical research. It is a type of protein separation method .It is one of the highly efficient techniques of analysis and sole method for separation of proteins for western blot, RNA studies etc. It is a both qualitative and quantitative analysis technique. Separation depend upon electrophoretic mobility.Electrophoresis technique are of various type like Moving boundary electrophoresis ,Zone electrophoresis ,Affinity electrophoresis ,Pulsed field electrophoresis ,Dielectrophoresis.this technique mainly used in antibiotic analysis,vaccine analysis DNA analysis and protein analysis as well as fingerprint analysis. KEYWORDS:Electrophoresis, Electrophoretic mobility,Zone Electrophoresis, Moving boundary Electrophoresis, Dielectricphoresis. INTRODUCTION Electrophoresis is a physical method of analysis based on the migration of electrically charged proteins, colloids, molecules or other particles dissolved or dispersed in an electrolyte solution in the direction of the electrode bearing the opposite polarity when an electric current is passed through it. Separations may be conducted in systems without support phases (such as free solution separation in capillary electrophoresis) or in stabilising media such as thin-later plates, filins or gels. The electrophoretic mobility is the rate of movement in metres per second of the charged particles under the action of an electric field of I volt per metre and is expressed in square metres per volt second.

Saylor Dr. Richard S. Miller Dr. Rui Qiao i ABSTRACT Controlled manipulation of synthetic particles and biological cells from a complex mixture is important to a wide range of applications in biology, environmental monitoring, and pharmaceutical industry. In the past two decades microfluidics has evolved to be a very useful tool for particle and cell manipulations in miniaturized devices. A variety of force fields have been demonstrated to control particle and cell motions in microfluidic devices, among which electrokinetic techniques are most often used. However, to date, studies of electrokinetic transport phenomena have been primarily confined within the area of microchannels. Very few works have addressed the electrokinetic particle motion at the reservoir-microchannel junction which acts as the interface between the macro (i.e., reservoir) and the micro (i.e., microchannel) worlds in real microfluidic devices.

Lapizco-Encinas * ID Microscale Bioseparations Laboratory and Biomedical Engineering Department, Rochester Institute of Technology, Rochester, NY 14623, USA; [email protected] (M.F.R.-C.); [email protected] (E.G.); [email protected] (D.V.P.) * Correspondence: [email protected]; Tel.: +1-585-475-2773 Received: 7 July 2017; Accepted: 30 July 2017; Published: 2 August 2017 Abstract: The analysis, separation, and enrichment of submicron particles are critical steps in many applications, ranging from bio-sensing to disease diagnostics. Microfluidic electrokinetic techniques, such as dielectrophoresis (DEP) have proved to be excellent platforms for assessment of submicron particles. DEP is the motion of polarizable particles under the presence of a non-uniform electric field. In this work, the polarization and dielectrophoretic behavior of polystyrene particles with diameters ranging for 100 nm to 1 µm were studied employing microchannels for insulator based DEP (iDEP) and low frequency (<1000 Hz) AC and DC electric potentials. In particular, the effects of particle surface charge, in terms of magnitude and type of functionalization, were examined. It was found that the magnitude of particle surface charge has a significant impact on the polarization and dielectrophoretic response of the particles, allowing for successful particle assessment. Traditionally, charge differences are exploited employing electrophoretic techniques and particle separation is achieved by differential migration. The present study demonstrates that differences in the particle’s surface charge can also be exploited by means of iDEP; and that distinct types of nanoparticles can be identified by their polarization and dielectrophoretic behavior.

The communication, technically referred to as connectivity, between single-neurons, is the center of many investigations aimed at elucidating pathophysiology, anatomical differences, and structural and functional features. In comparison with bulk analysis, single-neuron analysis can provide precise information about neurons or even sub-neuron level electrophysiology, anatomical differences, pathophysiology, structural and functional features, in addition to their communications with other neurons, and can promote essential information to understand the brain and its activity. This review highlights various single-neuron models and their behaviors, followed by different analysis methods. Again, to elucidate cellular dynamics in terms of electrophysiology at the single-neuron level, we emphasize in detail the role of single-neuron mapping and electrophysiological recording. We also elaborate on the recent development of single-neuron isolation, manipulation, and therapeutic progress using advanced micro/nanofluidic devices, as well as microinjection, electroporation, microelectrode array, optical transfection, optogenetic techniques.

  • Electrokinetic Fluidic Dielectrophoresis for Precise On-Chip Fluidic Routing
    Electrokinetic Fluidic Dielectrophoresis for Precise On-Chip Fluidic Routing By Edwin Lavi A thesis submitted to Johns Hopkins University in conformity with the requirements for the degree of Master of Science in Engineering Baltimore, MD May, 2018 © 2018 Edwin Lavi All Rights Reserved Abstract Recent developments in the field of microelectromechanical systems (MEMS) enable access to small low-cost precision analytical tools for use in biological, pharmaceutical, energy and space industries. In this thesis, we demonstrate a new method to control microfluidic fluid flows and analyte concentrations using on-chip solid-state electrokinetic switches. In particular, we demonstrate the ability to dynamically control spatial chemical concentration gradients for potential applications in studying biased cell motility during cellular chemotaxis. This work is an important development because it will enable the rapid and dynamic control of microfluidic concentration profiles which can be leveraged to better elucidate chemotactic features of motile cells. Currently, the most established chemotaxis assays are chamber and needle assays. These methods produce concentration gradients using passive chemical diffusion using a quasi-steady source of chemokine concentration. As such, it is difficult and time consuming to dynamically control these gradients during cell migration experiments. The goal of this thesis project is to integrate electrokinetics to enable a new class of precision and control of chemical gradients for directed cell migration studies on a single-cell level. In this paper, we leverage an electrokinetic phenomena, fluidic dielectrophoresis (fDEP) which occurs at liquid-liquid electrical interfaces that have been subjected to orthogonal externally applied electric fields. This field polarizes the fluid interface and produces an electrohydrodynamic stress and net fluidic motion, or displacement, in the direction perpendicular to the fluid flow.
