Preface

A biosensor is a potential device that covers medical, agricultural, economical, industrial, and medical applications. Over the past few decades, glucose biosensors have emerged as the most acceptable and reliable biosensors; they are inexpensive, fast, and reliable. Biosensors also play a very promising role in detecting and managing COVID-19 cases worldwide. It is notable that modernization, industrialization, and environmental damage have greatly impacted human lives over the past few decades and led to major health concerns. Nowadays, even after exhausting several resources to prevent and treat chronic diseases, the human world bears the never-ending global burden of diseases. In recent years, the development of biosensors has significantly influenced the healthcare sector due to the promising role of biosensors in healthcare management. Biosensors work on the principle of converting a biochemical signal to optical or electrical signals. Signal transduction and its performance depend upon the selection of materials and interaction in biosensors. The application of biosensors is not restricted to detecting, diagnosing, and treating a myriad of chronic diseases; it extends toward monitoring and managing patient health. Therefore, biosensor-based therapies have emerged as possible and crucial approaches to delivering point-of-care diagnostics that match and surpass conventional standards regarding specificity, sensitivity, time, response, accuracy, and cost. In this book, considering the growing number of cancer cases and fatalities due to late illness detection worldwide, we have covered several biosensors and biomarkers as possible tools for early cancer detection. In addition, this book focuses on many types of nanomaterials, such as gold nanoparticles, quantum dots, polymeric nanoparticles, carbon nanotubes, nanodiamonds, and graphene nanostructured materials, which are currently being utilized in biosensors for clean and healthy environments. The study includes the fundamental as well as modern biosensors and their sensitivity and specificity; it also sheds light on their significant applications with attractive prospects in different interdisciplinary fields. This book comprises several new efficient techniques for developing biomaterials to accelerate wound healing and bone tissue engineering. It would interest readers in the areas of health, agriculture, food, industries, and biomedical sciences-related research. Due to its quality content, this book will cater to the academic needs of a long range of readers.
