Nanotechnology of Cancer Therapy: An Overview

Nanotechnology is the study and use of structures between 1 nanometer and 100 nanometers in size. Nanotechnology is definitely a medical boon for diagnosis, treatment and prevention of cancer diseases. Nanoparticulate technology is of particular use in developing a new generation of more effective cancer therapies capable of overcoming many biological, biophysical and biomedical barriers that the body stages against a standard intervention. Nanoparticles that deliver chemotherapy drugs directly to cancer cells are under development. Nanomedicine application areas include drugdelivery, therapy, diagonistic, imaging and antimicrobial techniques. The formed nano particles can be used in wide range of therapeutic treatment of cancer. To overcome problems of systemic toxicity associated with chemotherapy and enhance treatment resolution of cancer therapies, nanotechnology is increasingly providing many novel approaches, especially to energy-based cancer therapies. Nonmaterial and biomarkers of cancer, general principle of drug targeting to cancer, intracellular mechanisms, and nanoparticles based formulation in market, several recent applications in medicine as diagnostic and therapeutic are discussed. This article aim to overview on all the parts of nanotechnology in cancer therapy.
