Nanobiotechnology is the application of nanotechnology in biological fields. Nanobiotechnology is a multidisciplinary field that currently engages researchers in conventional as well as advanced avenues of engineering and natural sciences.The recent developments in nanobiotechnology have impacted various socio-economic sectors, including medical, agriculture, food, textile, and other industries. Although the integration of nanomaterials with biology has led to the development of diagnostic devices, contrast agents, analytical tools, therapy, and drug-delivery vehicles, bionanotechnology research is still in its infancy. The full potential of developments in this field have yet to be realized. This book discusses various nano-engineered materials or nanocarriers that are used in different situations. It presents 8 chapters that cover the application of nanobiomaterials in environmental remediation, nanofertilisers, nanobiotics against antimicrobial resistance, nanobiosensors in pathogen detection, and nanotoxicity assessments. Each chapter is structured into easy-to-read sections that explain fundamental and applied concepts of nanobiomaterials. Readers will gain a current view of the biotechnological application of modern nanomaterials and nanoparticles. The book is intended to be a primer for students and researchers in agriculture, biotechnology, and biomedical engineering courses.
