Nanotechnology based drug delivery system: Current strategies and emerging therapeutic potential for medical science

Nanotechnology or Nano medicine has been identified as the dominant and most commercially invented technology that aims to improve the quality of health care strategies. Although nanotechnology has some limitations, many pharmaceutical and medical equipment companies have already adhered to medical nanotechnology. In some cases, drugs with high toxic potential, such as chemotherapeutic cancer drugs, can be administered with a better safety profile using nanotechnology. It is important to note that Living cells are tiny virtual machines involved in all biological activities, including cell signalling, metabolism, energy generation and nutrient transport. Therefore it can be considered a major candidate technology to deal with biology and medicine for therapeutic purposes. In this review, we discuss the importance of nanoscience with different nanotechnology platforms being used in other aspects of medicine. Besides, we are also addressing the future opportunities of nanotechnology in human health.
