This book describes the plasmonic photothermal-assisted multimodal cancer therapeutics in the area of cancer nanotechnology or cancer nanomedicine. This book covers the fundamentals of plasmonic photothermal cancer therapy as well as plasmonic photothermal mediated multimodal cancer therapy. The various steps involved in developing such therapeutic modality, viz. (a) the selection of suitable nanoparticles, (b) synthesis of multifunctional nanocomposite, (c) optimization of the photosensitizer and chemotherapeutic drug loadings, (d) characterization of the synthesized nanocomposite, and (e) therapeutic evaluations through novel tumor-tissue mimicking phantoms and the cancer cell lines are discussed in detail. Apart from the detailed description of therapeutic outcome, this book provides a step-by-step approach to develop a multifunctional nanocomposite for such therapeutics. Overall, this book provides simplified and in-depth information about cancer nanobiotechnology to the researchers and graduate students in subject areas of nanotechnology, biotechnology and pharmaceutics to develop and contribute to such multimodal cancer therapeutics.
