Nanotechnology is the study of tiny structures ranging in size from 0.1 to 100 nanometers. It includes biophysics, molecular biology, and bioengineering, as well as medical subspecialties such as cardiology, ophthalmology, endocrinology, oncology, and immunology. Pharmaceutical Nanotechnology combines the methods and ideas of nanoscience and nanomedicine with pharmacy to create novel medication delivery systems that transcend the limitations of traditional drug delivery systems. The purpose of this article is to provide an overview of nanotechnology and its uses in the pharmaceutical industry.

The study of different microscopic or tiny shaped and sized particles is what nanotechnology is all about. These nano-structured compounds have a wide range of strong actions in a variety of disciplines. These are readily carried due to their small size and form. Because of its small size, it may be used in a variety of ways. Nanotechnology improves a variety of businesses, including the pharmaceutical industry, the food industry, environmental protection, and a variety of others. The purpose of this article is to provide an overview of nanotechnology and its applications in different industries and areas.

Our main aim in the present investigation was to assess the cancer targeting potential of doxorubicin conjugated with folic acid (FA), ethylene di-amine (EDA) and surface F- MWCNTs (FA-EDA-MWCNTs- DOX) conjugate employing on MCF-7 (breast cancer cell line) for efficient tumor targeting. We developed a highly effective novel targeted drug delivery based on DOX-conjugated with the surface of F-MWCNTs by using nucleophilic substitution reaction mechanism and evaluated in facile strategy for cancer treatment. The in vitro drug release study shows that the percentage of drug release under an acidic condition pH-5.4 is higher than that under normal physiological conditions. The FA-EDAMWCNTs- DOX nano-conjugate affords higher efficacy in tumor growth suppression due to its stealth nature and most preferentially taken up by cultured MCF-7 cells through receptor-mediated endocytosis mechanism. Fourier Transform Infrared Spectroscopy (FTIR), UV-Visible Spectroscopy, Nuclear Magnetic Resonance Spectroscopy (NMR) and Scanning Electron Microscopy (SEM) measurements clearly confirmed the functionalization & conjugation steps. The results concluded that developed watersoluble nano-conjugate might emerge as “safe and effective” nano-medicine in cancer treatment by minimizing the side effects with generally regarded as a safe prominence.
