Nanomedicine is the medicinal diligence of nanotechnology (is the branch of engineering that deals with things smaller than 100 nanometers (especially with the manipulation of individual molecules)). The range of Nanomedicine from medical applications of nano-materials (is a field that takes a materials science-based approach to nanotechnology. It studies materials with morphological features on the nanoscale, and especially those that have special properties stemming from their nanoscale dimensions) to nano-electronic ((physics) the use of nanotechnology to create electronic components) biosensor (is an analytical device for the detection of an analyte that combines a biological component with a physicochemical detector component). The range can also be possible for future applications of molecular nanotechnology (a technology based on the ability to build structures to complex, atomic specifications by means of mechanosynthesis).

As we know that working with such a small thing is very complicated. The main and current problem for Nanomedicine is to understand the toxicity (is the degree to which something is poisonous or grave harmfulness or deadliness) and environmental impact of nanoscale materials. National Institute of Health, US, is giving funds for Nanomedicine research and setting up Nanomedicine centers. It is estimated in the journal Nature Materials (is focused on all topics within the combined disciplines of materials science and engineering. Topics published in the journal are presented from the view of the impact that materials research has on other scientific disciplines such as (for example) physics, chemistry, and biology) that 130 nanotech-based drugs and delivery systems were being established globally.

It is believed that Nanomedicine in the near future will provide valuable set of research joyrides and medically useful devices. That would be the great revolution in the field of medical science. Moreover, some other fields are trying to revolutionize medicine and medical field such as molecular nanotechnology (is a speculative subfield of nanotechnology regarding the possibility of engineering molecular assemblers, machines which could re-order matter at a molecular or atomic scale).It considers that cell repair machine(is a cell repair machine would be a device having a set of minuscule arms and tools controlled by a nanocomputer; the whole system could be much smaller than a cell) could transfigure the field of medicine. For the advancement of new therapies, drug delivery systems and in vivo (is experimentation using a whole, living organism as opposed to a partial or dead organism, or an in vitro ("within the glass", i.e., in a test tube or petri dish) controlled environment) imaging, pharmaceutical industry is seeking the best way for new commercials.

There are some other interfaces that are considered to be the active goal for Nanomedicine research like neuro-electronic (is a visionary goal dealing with the construction of nanodevices that will permit computers to be joined and linked to the nervous system) and nanoelectronics ((physics) the use of nanotechnology to create electronic components) based sensors.

The use of nanomaterials in the field of Nanomedicine is of great importance. Nano-medical centers are trying to approach drug delivery (is the method or process of administering a pharmaceutical compound to achieve a therapeutic effect in humans or animals) centers for the development of nanoscale particles or molecules or to improve drug bioavailability ((pharmacology) the amount of drug which reaches the site of physiological activity after administration). Over a period of time, drug delivery emphases on maximizing bioavailability and this maximization can be attained by molecular targeting via nano-engineered devices. The nano-engineered materials might be effective in the treatment of diseases and illnesses for example, cancer.
