This book primarily focuses on nanomaterial synthesis, properties, sensor fabrication, and their uses for disease diagnosis and therapy. Major topics covered include synthesis of different dimensional nanomaterials, characterizations and analysis of nanomaterials, procedure for non-invasive disease diagnosis, and measurement principles of medical devices or sensor devices. It also illustrates state-of-the-art nanomaterials for drug delivery supported by practical examples and case studies. Features: Explores different dimensional (0D, 1D, 2D, 3D) nanomaterial synthesis techniques. Introduces various nanomaterials for fabrication sensors. Discusses the applications of sensors in disease diagnostics and therapy. Covers nanomaterial characterizations techniques such as XRD, FESEM, AFM, and TEM. Describes state of the art nanomaterials for drug delivery. This book is aimed at graduate students and researchers in materials science, nanomaterials, sensors, and biosensors.
