Book Description
This book presents an investigation of gigaseal formation using micro/nanotechnology. The aims of the book are twofold. First, it explains the mechanisms of gigaseal formation using the latest discoveries. Second, it provides practical techniques for frequent formation of high resistance seals. The formation of a high-resistance electrical seal, also known as a gigaseal, between a cell membrane and a glass micropipette tip is essential in patch-clamp experiments. Even though four decades have passed since the introduction of the patch-clamping technique by Neher and Sakmann, gigaseal formation remains an obstacle in developing the high-throughput ion channel screening systems required by the pharmaceutical industry. Here the authors share their latest methods for achieving gigaseal formation and describe techniques that are highly desirable at both research and industrial levels. Nanotechnology has been found to be a powerful tool for studying and modifying glass micropipettes and in tackling the problem of gigaseal formation.

Book Description
This PhD project is set out to study the mechanism of gigaseal formation and to provide techniques which enable the frequent formation of high resistance seals. Such techniques are highly desirable at both research and industrial levels. The research can be divided into three main sections. In the first section the most important factors in seal formation were identified. Then a group of novel approaches have been developed to alter these factors and achieve better sealing conditions. In the second section the effect of roughness, hydrophilicity and tip size on gigaseal formation has been studied. Patch clamp experiments were carried out using conventional and treated pipettes. In the third section of this research, glass micropipettes were characterized using various measurement techniques. The proposed techniques in this thesis not only explain the gigaseal formation in more detail, but also provide techniques to increase both the seal resistance and probability of seal formation. FIB polished pipettes improved the seal resistance significantly and chemically treated pipettes resulted in the formation of seals for more than 80% of trials. Therefore the research aims have been successfully met.

Book Description
ß-barrel outer membrane channel proteins (OMP) are useful as robust and flexible models or components in nanotechnology. Over the last decade biotechnological techniques allowed to expand the natural characteristics of OMPs by modifying their geometry and properties. The present book is oriented towards a broad group of readers including graduate students and advanced researchers. It gives a general introduction to the field of OMP based nano-component development as well as the state of the art of the involved research. On the example of the E. coli FhuA the transformation of an OMP into a tailored nano-channel will be outlined. An exhaustive description of the scientific strategy, including protein selection, analytical methods and “in-silico” tools to support the planning of protein modifications for a targeted application, consideration on the production of a custom made OMP, and an overview on technological applications including membrane/polymersome technology, will be provided.

Book Description
Ion channel research has increased tremendously in the past 35 years since the first publication of the patch clamp technique by Neher and Sakmann in 1976. This is documented by the rising number of publications listed in Pubmed (http://www.ncbi.nlm.nih.gov/pubmed) including the keyword ‘ion channel’ from just 186 hits in 1976 to almost 180,000 hits today. Ion channels attract this great interest due to their pivotal role in the control of fundamental physiological processes in a plethora of different tissues. Moreover, their importance in a wide range of inherited and drug-induced pathologies spanning all major therapeutic areas makes them attractive targets for pharmacological drug screening and potential risk factors when assessing drug safety (Ashcroft, 2006; Clare, 2010; Dunlop 2008; Milligan 2009). Several methods and technologies have been developed to meet the analytical needs for studying ion channels. These approaches have addressed ion channel function directly as well as in the context of the cell and tissue. Scaling of these technologies has allowed ion channel analysis to be carried out on high throughput and high content assay systems. In this Research Topic we want to provide an up-to-date collection of the latest developments and improvements in ion channel screening; defining the cutting edge and indicating further developments required in the future.

Book Description
Patch clamping is a widely applied electrophysiological technique for the study of ion channels; membrane proteins that regulate the flow of ions across cellular membranes and therefore influence the physiology of all cells. Patch Clamping aims to cover the basic principles and practical applications of this important technique. Starting with a review of the history of patch clamping, the text then goes on to cover the basic principles, platforms, equipment and environmental control, and will also include coverage of preparation types, recording modes and analysis of results. This book will explain the basic principles and practical application of patch clamp electrophysiology Written in a non-technical style to ensure its broad appeal to novice users Takes a practical approach This self-contained guide provides everything a practising patch clamp electrophysiologist needs to know to master this technique, including an overview of membrane biophysics, standard experimental design, data analysis, and technical concerns

Book Description
This volume focuses on the modulation of biological membranes by specific biophysical properties. The readers are introduced to emerging biophysical approaches that mimick specific states (like membrane lipid asymmetry, membrane curvature, lipid flip-flop, lipid phase separation) that are relevant to the functioning of biological membranes. The first chapter describes innovative methods to mimic the prevailing asymmetry in biological membranes by forming asymmetrical membranes made of monolayers with different compositions. One of the chapters illustrates how physical parameters, like curvature and elasticity, can affect and modulate the interactions between lipids and proteins. This volume also describes the sensitivity of certain ion channels to mechanical forces and it presents an analysis of how cell shape is determined by both the cytoskeleton and the lipid domains in the membrane. The last chapter provides evidence that liposomes can be used as a minimal cellular model to reconstitute processes related to the origin of life. Each topic covered in this volume is presented by leading experts in the field who are able to present clear, authoritative and up-to-date reviews. The novelty of the methods proposed and their potential for a deeper molecular description of membrane functioning are particularly relevant experts in the areas of biochemistry, biophysics and cell biology, while also presenting clear and thorough introductions, making the material suitable for students in these fields as well.
