Summary:

"This book will cover all aspects of using nanozymes for environmental safety, monitoring and remediation. It will uncover the way nanozymes are being used for sensing different categories of environmental pollutants like pesticides, heavy metals, organic pollutants or microbes. Further, it will provide information on using nanozymes for extraction, removal or remediation of pollutants from soil or water samples and their degradation to relatively safer by-products. This book will also include the challenges to be met by nanozymes and their future prospects"-- Provided by publisher.
