Nanobots: Development and Future

Abstract

Some decades ago, nanoscale machines called “nanorobots” (better known as “nanobots”) were only in science fiction. Today, they are expected to be the next generation of nanodevices and to change the technology related to medical diagnosis and drug delivery. Many challenges have to be faced to develop this technology; not only from the technical, biological and physicochemical point of view but also concerning the risks of using new materials and devices at nanoscale and their interaction with the environment and human beings. The aim of this review is to describe the nanobots, the technology and advances and in more detail the applications related to medicine.
