Point-of-care testing devices for early detection, screening and diagnosis have been proven to significantly improve patient survival rates and quality of life, as well as to significantly reduce the cost and complexity of disease treatment. Providing a timely update on the current understanding of paper-based biosensors, this book aims to deal with the current state-of-the-art of paper-based biosensors technology and addresses its future prospects for the detection of infectious diseases, with particular relevance and applications for low-income and developing countries. This book focuses on the design and fabrication strategies of paper-based devices for the detection of various biomolecules in biomedicine. This comprehensive research and reference text would be suitable for researchers, scholars, and manufacturers in multiple disciplines, such as medical device design.
