PRINTED IN THE UNITED STATES OF AMERICA About theAuthors JOHN M. WALKER has been a Readerin Protein Chemistry in the Divisionof Bi- ological Sciences, Hatfield Polytechnic, Hatfield, Harts, England, since 1980.Be- fore that he was a postdoctoralresearch scientist at the Institute of CancerRe- search, London, for eight years.Walker received a 1st Class Honors Degreein Chemistry and a Ph.D. in Biological Chemistry from University College,Lon- don. For many years he was involved in studies on nonhistone chromosomal pro- _ teins. At Hatfield Polytechnic he hasbeen increasingly interested in algal biotechnology (particularlythe use of algae as a sourceof novel pharmaceutical compounds) and in studiesof the factors responsible for protein stability (using proteinengineering methodology). Walker is coordinator of the HatfieldPolytechnic Biotechnology Unit. Since 1981 he has been theorganizer of highly successful In- troductory Workshops in Techniquesin Molecular Biology. These workshops are held annually atHatfield, and are also run in Yugo- slavia, Norway, Pakistan, and India.He is coorganizer of Molecular Biology and Biotechnology, aone-week Royal Society ofChemistry residential school held at Hatfield every two years.In addition, he has served as editor of a numberof books on molecular biologymeth- odology. MICHAEL COX is a Reader in Applied Chemistry at Hatfield Polytechnic, Hat- field, Harts, England, and lectures in the field; of inorganic chemistry, chemical technology, and biotechnology. In 1987 he was granted the title of Pm fessor in recognition of his research activities. He received M.Sc. and Ph.D. degrees from University College, London. Following a sabbatical at Warren Spring Laboratory, Department of Indus- try, Cox became interested in liquid-liq- uid extraction and ion exchange recovery of metals from waste feeds, a topic in which he is still actively en- gaged. This led to a general interest in downstream processing of process streams, including those derived from fermentation. Cox is the author of many research papers and review articles. For many years he served on the Committee of the Solvent Extraction and Ion Exchange Group of the Society of Chemical Industry, com- pleting a term as Chairman in 1988. 7 Preface To define the term "biotechnology" or todescribe the role of a biotechnologist is never easy. Such broad termsoften mean different things to different people. As a startingpoint, let us define biotech- nology as the practical application of biological systemsto the man- ufacturing and service industries and to the managementof the environment. Yet such a brief description ignores the widespectrum of related disciplines that must come together tocommercialize a biological process. At ons end of the spectrum,biotechnology involves work at the laboratory bench level, often aimed atidentifying or constructing microorganisms or cells capable of providingproducts of economic value. This aim can be achieved by themolecular biologist who applies new methodologies that arisefrom developments in the biological sciences, especially in genetic engineering, tomicroorgan- isms, plant cells, or animal cells. Alternatively,microbial screening programs (which can involve amultidisciplinary team of microbiol- ogists, pharmacologists, biochemists, andchemists) can result in the identification of microorganismsproducing potentially useful metabolites. Once the organism or cell of interest isobtained, it is necessarY to develop the growth of the microorganism,animal cell, or plant cell on a large scale in aneconomically viable process. However,in plant biotechnology, growth of appropriatelymodified cells to give a plant with novel characteristics can sometimesbe the ultimate goal. Scale-up involves both the microbiologist'sknowledge of microbial _ physiology-biochemistry and fermentationtechnology and the bio- chemical or chemical engineer'sknowledge of reactor design, heat and mass transfer, and process control.Recovery of the desired prod- uct takes us into the area ofdownstream processing, which requires expertise in areas such as chemistry,biochemistry, and chemical engineering to develop the variouslarge-scale methodologies for .vii concentrating, extracting, and purifying the required product as eco- nomically as possible. The diverse applications of biotechnological processes range from waste treatment and odc r control to the production of reagentsfor the diagnosis and treatr lent of disease. Enzymes, for example, are used in a variety of pro:asses, including enzyme reactors, washing powders, biosensors, and diagnostic kits. The use of genetic engi- neering, via site-directed mutagenesis, to design more stable en- zymes for use in these biotechnological processestakes us back to the beginning of our biotechnology spectrum. The typical biotechnologist will probably be an expert in oneof these areas, but

  • Biotechnology: Answers to Common Questions
    FSR0030 Biotechnology: Answers to Common Questions Kevin Keener, Assistant Professor of Food Science Thomas Hoban, Professor of Sociology and Food Science N.C. Cooperative Extension Service N.C. State University We are entering the “Century of Biology.” Recent developments in the biological sciences are giving us a better understanding of the natural world. At the same type we are developing new tools that are collectively referred to as “biotechnology.” These help us address problems related to human health, food production, and the environment. Any new technology – particularly one as far-reaching as biotechnology – will generate interest, as well as concerns. Because the science behind biotechnology is complex, misconceptions arise over its impacts and implications. In this publication we will answer questions many people have about biotechnology. These questions are organized along the lines of a news story: what, when, who, where, why, and how. We also provide a list of additional information sources available on the Internet. Our primary focus will be on the uses of biotechnology in agriculture and food production since these appear to be more controversial than other applications (at least up until this time). What is Biotechnology? In its broadest sense, biotechnology refers to the use of living systems to develop products. New scientific discoveries are allowing us to better understand fundamental life processes at the cellular and molecular level. Now we can improve selected attributes of microbes, plants, or animals for human use by making precise genetic changes that were not possible with traditional methods. All living organisms contain genes that carry the hereditary traits between generations.

  • 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.
