Fabrication and Advanced Applications of Nanomaterial-Based Electrochemical Sensors will help students understand the concept of nanomaterial-based electrochemical sensors easily by giving simple examples and illustrations. Electrochemical sensors can determine various bioactive compounds and organic molecules, but the further addition of nanomaterials into the electrode can increase the detection limit due to their excellent electrical and chemical properties and their huge surface area. Nanomaterial-based electrochemical sensors can also detect toxic waste and thereby reduce the risk of waterborne diseases to both humans and aquatic animals. This book seeks to enhance environmental awareness and explain how electrochemical sensors contribute to a more sustainable and conscious way of living. The book will be useful for researchers who are fabricating various nanomaterial-based electrodes to determine neurotransmitters, organics, toxic dyes, surfactants, and various bioactive compounds as well as engineering, chemistry, electrochemistry, and nanomaterial students at the undergraduate and postgraduate level. Key Features: • The first book to cover novel applications of nanomaterial-based electrochemical sensors. • Discusses various nanomaterials and composite materials as modifiers for the electrochemical determination of different dyes, pesticides, toxic chemicals, neurotransmitters, food additives, and heavy metals. • Describes the facilitation of nanomaterial-based electrochemical sensors as compared with other conventional modifiers.
