The design and fabrication of aptamer-based biosensors for point-of-care testing of disease diagnostic and prognostic is an upthrust and interdisciplinary area of research. This book covers the design and development of novel cost-effective aptamer-based biosensors for disease diagnostic and prognostic including an understanding of health care management in terms of timely updates of disease situations in a particular geographical area. It also discusses the scaling up and market trend of aptamer-based devices for extension of research from lab to market, and end users. Features: Explains the design and fabrication of aptasensors-based diagnostic devices Includes novel approaches and comprehensive technology overview for diagnosis management towards early-stage detection of various biomarkers associated with several health conditions Demonstrates possible benefits of combined diagnostics and therapeutic possibilities using aptamer-based point-of-care technologies devices Discusses emerging implications and recent advances of biosensing platforms for designing and developing aptamer-based point-of-care testing (POCT) devices Explores aptamer-based approach to develop advanced platforms for medical applications and open arena for state-of-the-art future research This book is aimed at researchers and graduate students in biomedical engineering, diagnostics, nanobiotechnology, and materials science.
