ABSTRACT
Nanomedicine is verily a science dealing with monitoring, repairing, construction, and control of human biological systems at the nanoscale and molecular level, especially during pathological states. Several engineered nanodevices and nanostructured materials have been explored for research and some have been subsequently developed for wide-ranging applications in nanomedicine after surmounting myriad challenges. The scientists and researchers, accordingly, have to undertake the onerous task of making apt modifications in the physicochemical characteristics of such nanomaterials and nanodevices. Nanodevices, in particular, possess various unique properties, such as optical, magnetic, chemical, and structural properties, with promising applications in the medical field. Nanomedicine is a very broad research field encompassing diverse devices and medical imaging, all intended to improve healthcare. The present book chapter endeavours to present an explicit account on utilization of nanotechnological paradigms to engineer therapeutic agents, regenerative applications, sensing, and bioimaging using different contrast agents and diagnostic tools.
