Book excerpt: Technology is significantly affected by a material’s ability to adapt to its environment in a beneficial way. These smart systems, in which material qualities react to outside stimuli, are currently being developed. These materials have the potential to significantly improve the performance of new systems by lowering size, weight, cost, power consumption, and complexity while enhancing effectiveness, safety, and adaptability. Materials can be multifunctional on a variety of temporal and compositional levels and at dimensions ranging from nano to macro. Innovative Multifunctional Nanomaterial for Photocatalysis, Sensing, and Imaging clarifies the type, chemical composition, and applications of multifunctional nanomaterials in photocatalysis, sensing, and imaging. This book discusses the most current advances in multifunctional materials for photocatalysis, sensing, and imaging in biological systems. Covering topics such as drug development, nanoparticles, and sensing, this premier reference source is an excellent resource for chemists, engineers, professionals, students and educators of higher education, researchers, and academicians.
