Available in PDF, EPUB and Kindle. Book excerpt: During most of the twentieth century, direct study of individual polymer molecules was impossible due to their small size. Therefore, polymers were typically studied in bulk solutions, and their behavior and interactions had to be understood through average bulk property measurements. Because the scale of most industrial applications greatly exceeded the size of these molecules, this level of analysis was satisfactory. In the last twenty years, however, the appearance of microfluidic devices, whose smallest length scales are comparable to the size of a polymer molecule, has offered ways to visually study the behavior of individual polymer molecules and made possible new and exciting applications that exploit the precise control afforded by the small size of these devices. One such application is gene mapping, which extracts, at a. coarse level, the information embedded in the base pair sequence of genomic DNA. This technology relies on the ability to manipulate single DNA molecules in order to perform such tasks as separating DNA based on length and stretching DNA away from its entropically coiled equilibrium state. Recently, many novel methods have been proposed to accomplish these tasks using microfabricated devices, and munch experimental work has been focused on identifying and characterizing the underlying physics governing these devices. Current understanding, however, is greatly hampered by the fact that experiments can only provide limited information about the behavior of DNA molecules (e.g., they are unable to resolve details on small time and length scales). Therefore, simulations are an invaluable tool in the study of DNA behavior in microfiuidic devices by complementing and guiding experimental investigations. In this thesis, we present Brownian Dynamics simulations of the single molecule behavior of DNA in microfluidic devices related to gene mapping. In particular, we have considered the use of a post array to "precondition" the configuration of molecules for subsequent stretching in a contraction and compared our results to previous experiments. We found good qualitative agreement between experiments and simulations for DNA behavior in the post array, but our simulations consistently overpredicted the final stretch of molecules at the end of the contraction, which we attributed to nonlinear electrokinetic effects. We also investigate the electrophoretic collision of a DNA molecule with a. large, ideally conducting post. Field-induced compression was shown to play a critical role in the escape process of a molecule trapped on the post surface, and an extensive theoretical analysis is performed, describing both the local field-induced compression and the larger collision problem. Finally, we study the relaxation process of an initially stretched molecule in slit-like confinement. We present the first simulation results that exhibit two distinct relaxation times in the linear force regime, as previously reported in recent experiments. Our analysis is focused on the experimentally inaccessible dynamics in the transverse directions, particularly at short times and on small length scales. Comparisons to the predictions of a recent mechanistic model of confined relaxation were found to be satisfactory.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Microfluidics may well be to the first half of the 21st century what microelectronics was to the latter half of the 20th century. The development of the integrated circuit allowed electrical devices to shrink from room-sized to pocket-sized, all the time increasing in speed and penetrating into nearly every aspect of our lives. Similarly, it is hoped that many of the large, expensive chemical and biological analyses currently being performed can be replaced by integrated microfluidic devices, often called labs-on-chip, resulting in a similar revolution. The scope of this thesis is best broken down into two parts. The first part will concentrate on the development of a theoretical and numerical framework for conducting microscale fluidic, thermal and biological simulation for electrokinetic processes and lab-on-chip devices. The analytical techniques and BLOCS (B & barbelow;io-L & barbelow;ab-O & barbelow;n-a-C & barbelow;hip S & barbelow;imulation) numerical code developed as part of this effort are demonstrated through a series of examples ranging from enhanced species mixing to joule heating in polymeric microchips to DNA hybridization kinetics. The second part of the thesis concerns a microfluidics based and electrokinetically operated DNA hybridization chip. The chip development is detailed from the construction of a microfluidics/biochip test bench for chip operation, transport/thermal visualization and on-line hybridization detection, to the development of a rapid prototyping microfabrication facility through to the actual design, construction and operation of the device. The electrokinetic control of the chip and microfluidic implementation is shown to enable nanolitre scale samples to be dispensed to the hybridization array and allow for simultaneous hybridization, removal of non-specific adsorption and perform quantitative analysis all in less than 5 minutes.

Available in PDF, EPUB and Kindle. Book excerpt: This Springer Handbook provides, for the first time, a complete and consistent overview over the methods, applications, and products in the field of marine biotechnology. A large portion of the surface of the earth (ca. 70%) is covered by the oceans. More than 80% of the living organisms on the earth are found in aquatic ecosystems. The aquatic systems thus constitute a rich reservoir for various chemical materials and (bio-)chemical processes. Edited by a renowned expert with a longstanding experience, and including over 60 contributions from leading international scientists, the Springer Handbook of Marine Biotechnology is a major authoritative desk reference for everyone interested or working in the field of marine biotechnology and bioprocessing - from undergraduate and graduate students, over scientists and teachers, to professionals. Marine biotechnology is concerned with the study of biochemical materials and processes from marine sources, that play a vital role in the isolation of novel drugs, and to bring them to industrial and pharmaceutical development. Today, a multitude of bioprocess techniques is employed to isolate and produce marine natural compounds, novel biomaterials, or proteins and enzymes from marine organisms, and to bring them to applications as pharmaceuticals, cosmeceuticals or nutraceuticals, or for the production of bioenergy from marine sources. All these topics are addressed by the Springer Handbook of Marine Biotechnology. The book is divided into ten parts. Each part is consistently organized, so that the handbook provides a sound introduction to marine biotechnology - from historical backgrounds and the fundamentals, over the description of the methods and technology, to their applications - but it can also be used as a reference work. Key topics include: - Marine flora and fauna - Tools and methods in marine biotechnology - Marine genomics - Marine microbiology - Bioenergy and biofuels - Marine bioproducts in industrial applications - Marine bioproducts in medical and pharmaceutical applications - and many more...
