%X Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. nanotechnology enhanced materials will enable a weightreduction accompanied by an increase in stability and an improved functionality. biomedical nanotechnology, bionanotechnology, and nanomedicine are used to describe this hybrid field. The pace ofnew discoveries in biotechnology and health care and even the appearance of whole new fields of endeavour in recent years have made for an exciting and challenging time for pharmacists.The increasingdemands of understanding how modern medicines work at the molecular level, the shift towards predictive, preventive and personalised health care and challenges from nanotechnology and stem cell technology have added to the need for pharmacists to remain the experts in medicines.Nanotechnology is on its way to make a big impact in Biotech, Pharmaceutical and Medical diagnostics sciences. A dynamic collaboration is observed within the Researchers, Government, Pharmaceutical - Biomedical companies and educational institutions all over the world in developing the nanotechnology applications in advanced medicine and patient care. It is expected that the forthcoming generations of nano products will have target specificity,may carry multiple drugs, and could potentially release the payloads at varying time intervalsThe prefix "nano" refers to one-billionth. When applied in the metric scale of linear measurements, a nanometer is one-billionth of a meter. The term "nanotechnology" is now commonly used to refer to the creation of new objects with nanoscale dimensions between 1.0 and 100.0 nm.Functionalities can be added to nanomaterialsby interfacing them with biological molecules or structures. The size of nanomaterials is similar to that of most biological molecules and structures; therefore, nanomaterials can be useful for both in vivo and in vitro biomedical research and applications. Thus far, the integration of nanomaterials with biology has led to the development of diagnostic devices, contrast agents, analytical tools, physical therapy applications, and drug delivery vehicles. Nanotechnology is also opening up new opportunities in implantable delivery systems, which are often preferable to the use of injectable drugs, because the latter frequently display firstorder kinetics (the blood concentration goes up rapidly, but drops exponentially over time). This rapid risemay cause difficulties with toxicity, and drug efficacy can diminish as the drug concentration falls below
