An essential guide that puts the focus on method developments and applications in aptamers In recent years, aptamer-based systems have been developed for a wide-range of analytical and medical applications. Aptamers for Analytical Applications offers an introduction to the topic, outlines the common protocols for aptamer synthesis, as well as providing information on the different optimization strategies that can obtain higher affinities to target molecules. The contributors?noted experts on the topic?provide an in-depth review of the characterization of aptamer-target molecule interaction and immobilization strategies and discuss the developments of methods for all the relevant applications. The book outlines different schemes to efficiently immobilize aptamers on substrates as well as summarizing the characterization methods for aptamer-ligand complexes. In addition, aptamer-based colorimetric, enzyme-linked, fluorescent, electrochemical, lateral flow and non-labeling analytical methods are presented. The book also reflects state-of-the-art and emerging applications of aptamer-based methods. This important resource: -Provides a guide to aptamers which provide highly specific and sensitive molecular recognition, with affinities in the range of antibodies and are much cheaper to produce -Offers a discussion of the analytical method developments and improvements with established systems and beyond -Offers a comprehensive guide to all the relevant application areas -Presents an authoritative book from contributors who are noted experts in the field Written for analytical chemists, biochemists, analytical researchers, Aptamers for Analytical Applications is a comprehensive book that adopts a methodological point of view to the important aspects of aptamer generation and modification with a strong emphasis on method developments for relevant applications.

This book outlines comprehensively the main medical uses of aptamers, from diagnosis to therapeutics in fourteen chapters. Pioneering topics covered include aptamer pharmaceuticals, aptamers for malign tumors, aptamers for personalized therapeutics and aptamers for point-of-care testing. The book offers an essential guide for medical scientists interested in developing aptamer-based schemes for better theranostics. It is therefore of interest for not only academic researchers, but also practitioners and medical researchers in various fields of medical science, medical research and bio-analytical chemistry.

This book focuses on recent and future trends in analytical methods and provides an overview of analytical chemistry. As a comprehensive analytical chemistry book, it takes a broad view of the subject and integrates a wide variety of approaches. The book provides separation approaches and method validation, as well as recent developments and applications in analytical chemistry. It is written primarily for researchers in the fields of analytical chemistry, environmental chemistry, and applied chemistry. The aim of the book is to explain the subject, clarify important studies, and compare and develop new and groundbreaking applications. Written by leading experts in their respective areas, the book is highly recommended for professionals interested in analytical chemistry because it provides specific and comprehensive examples.

This is the first book to detail bioanalytical technologies and methods that have been developed using aptamers in analytical, medical, environmental, and food science applications. After an introduction to aptamers, aptamer targets, and their general uses, it discusses different applications with particular attention to the comparison between aptamer-based biosensors and methods versus the corresponding immunosensors. Examples of aptamer-based diagnostic techniques include whole-cell protein profiling (proteomics) and medical diagnostics for the distinction of diseased versus healthy states. This is a core reference for analytical chemists, electrochemists, pharmaceutical/medicinal chemists, biotechnologists, and others.

Nature has long used nucleic acid aptamers and enzymes for regulatory activities, such as the recently discovered “riboswitches” involved in gene expression. The existence of a large array of natural and artificial functional nucleic acids has generated tremendous enthusiasm and new opportunities for molecular scientists from diverse disciplines to devise new concepts and real applications that take advantage of those nucleic acids for sensing and other analytical applications. This book provides a timely and comprehensive overview of recent advances in the field, from leading experts in biology, chemistry, and engineering. A variety of topics are covered, from fundamentals of functional nucleic acids, to their applications as sensors, to nanotechnologies; as well as integration of functional nucleic acids into practical analytical systems.

Aptamers for Food Applications: Safety, Authenticity, and Integrity outlines the main applications of aptamers to ensure food safety, quality and compliance that are crucial for food science, public health and human sustainability. Aptamers or aptamer-based analytical devices are comprehensively summarized to tackle various food contamination or food adulteration problems. Topics covered in this book include aptamers for foodborne microbial pathogens, pesticide or veterinary drug residues, heavy metals, biotoxins, abused food additives, illegal food adulterants, POPs, GMOs, food allergens and food contact material migrants. It is therefore of interest for not only analytical investigators and food safety inspectors, but also regulatory practitioners and risk assessors in various food science and research fields. Presents the versatilities of aptamers for food safety, quality and compliance Provides utilities of aptamers for the analysis of almost all risk factors in foodstuffs Includes food quality control and regulatory measures such as HACCP, MRLs, proficiency test and uncertainty assessment, along with case illustrations
