Nanotechnology presents an entirely new era in the area of applied medical
science, from diagnosis to treatment or prevention of various diseases. This chapter
reviews the principle of nanotechnology and the wide range of its applications within
the medical science boundaries. Targeted drug delivery, improved image-formation
techniques, and advanced diagnostic tools constitute the most diversified applications
in nanomedicines, which include the use of nanoparticles, nanorobots, and
nanosensors. One of the applications of nanotechnology in medicine has marked a
paradigm shift toward extremely personalized medicine where highly particular
treatment plans can become possible. This chapter will therefore describe the type of
nanomaterials deployed for medical applications, the functional mechanism of these
materials, and potential benefits and risks from their use. The discussion also considers
the recent breakthroughs in this area of study and those that are under research with
promising prospects for transforming health care through nanotechnology. Only by
comprehending the intersection of nanotechnology and medicine will researchers and
medical professionals recognize the potential benefits of these breakthroughs for
patients with complex issues.
