Advances In Biosensors Research

There is a worldwide effort towards the development of bioanalytical devices that can be used for detection, quantification and monitoring of specific chemical species. In this context, biosensors represent an emerging trend in the diagnostics industry. A biosensor is a device that has a biological sensing element either intimately connected to or integrated within a transducer. The aim is to produce a digital electronic signal that is proportional to the concentration of a specific chemical or a set of chemicals. Biosensors are specific, rapid, cost-effective and easy to use devices that can be employed with minimal sample treatment. Biosensors have applications in many areas such as biotechnology, healthcare, pollution monitoring, food and agriculture product monitoring, the pharmaceuticals industry and defense. This reference text is devoted to the principles and applications of biosensors and meets the needs of academic institutes, research laboratories and the rapidly developing biosensor industry. Discusses novel ways that can be used to fabricate biosensors for a variety of applications Biosensors have applications in many scientific areas Contributors are experts in their respective fields of research

Advanced Biosensors for Health Care Applications highlights the different types of prognostic and diagnostic biomarkers associated with cancer, diabetes, Alzheimer's disease, brain and retinal diseases, cardiovascular diseases, bacterial infections, as well as various types of electrochemical biosensor techniques used for early detection of the potential biomarkers of these diseases. Many advanced nanomaterials have attracted intense interests with their unique optical and electrical properties, high stability, and good biocompatibility. Based on these properties, advanced nanoparticles have been used as biomolecular carriers, signal producers, and signal amplifiers in biosensor design. Recent studies reported that there are several diagnostic methods available, but the major issue is the sensitivity and selectivity of these approaches.

Advances in biosensors have improved biomarker discovery, affinity receptor design, detection of infectious microorganism and disease diagnostics due to close interaction of nanotechnology with other technologies which play a critical role for the future of biosensors and health care. Biosensing technology is a fascinating field which provides reliable, rapid and sensitive platforms for specific and ultra-sensitive biomarker-based diagnosis of diseases such as cancer, diabetes, infectious diseases and neurodegenerative disorders. This technology can also be used for the detection and removal of toxic materials from the human body such as cadmium, iron, aluminium and mercury. This book discusses advances in biosensors research.

This book focusses on recent advances and different research issues in the biosensor technology and also presents theoretical, methodological, well-established and validated empirical work dealing with the technology. The book addresses challenges for the development of a point-of-care test platform. The book also describes printed chip-based assay (Lab-on-a-Chip, Lab-on-a-PCB) for rapid, inexpensive, multiplex detection of disease biomarkers in real samples. It aims to overcome existing barriers for Lab-on-a-Chip commercialization (lack of cost effective mass manufacturing methods, self-contained, fully autonomous operation and user-friendliness). Different advanced techniques including electrochemical, optical, mass, colorimetric and signal amplification strategies describe early stage disease diagnosis. The book gathers scientific and technological novelties and advancements already developed or under development in the academic and research communities. It covers a vast audience from basic science to engineering and technology experts and learners.

Biosensors have captured the imagination of the world's scientific and commercial communities by combining interdisciplinary skills of biologists, physicists, chemists and engineers to provide innovative solutions to analytical problems. Biosensors are applicable to clinical diagnostics, food analysis, cell culture monitoring, environmental control and various military situations. Ever increasing demands for rapid and convenient analyses of a wide variety of materials in diverse locations have led to intense interest in the fusion of biology and electronics which mimics our principal concern - the effect of materials and environments on living systems. This series, "Advances in Biosensors", will present a compendium of research papers, in which eminent authorities in the field of biosensors provide an up-to-date overview of their laboratory's contribution, summarizing the primary scattered, in the journal and conference literature and reflecting on their findings.

The present book is devoted to all aspects of biosensing in a very broad definition, including, but not limited to, biomolecular composition used in biosensors (e.g., biocatalytic enzymes, DNAzymes, abiotic nanospecies with biocatalytic features, bioreceptors, DNA/RNA, aptasensors, etc.), physical signal transduction mechanisms (e.g., electrochemical, optical, magnetic, etc.), engineering of different biosensing platforms, operation of biosensors in vitro and in vivo (implantable or wearable devices), self-powered biosensors, etc. The biosensors can be represented with analogue devices measuring concentrations of analytes and binary devices operating in the YES/NO format, possibly with logical processing of input signals. Furthermore, the book is aimed at attracting young scientists and introducing them to the field, while providing newcomers with an enormous collection of literature references.

Today, biosensors are broadly applied in research, clinical diagnosis and monitoring, as well as in pharmaceutical, environmental or food analysis. In this work, the author presents the essentials that advanced students and researchers need to know in order to make full use of this technology. This includes a description of biochemical recognition elements, such as enzymes, antibodies, aptamers or even whole cells. Various signal transducers such as electrochemical and optical transducers, luminescence devices and advanced techniques such as quartz crystal microbalances and MEMS systems are covered as well. Current applications are introduced through various case studies, rounded out by a forward-looking chapter on the prospects for biosensor development offered by nanotechnology, lab-on-a-chip, and biomimetic systems.
