Nanotechnology for Cancer Treatment: An Introduction

Cancer is the leading cause of death worldwide. The treatment of cancer remains a challenge for medical professionals. Although various options, like chemotherapy, radiation, and surgery, are available to manage cancer, their use could be limited due to serious adverse effects. Therefore, advancements are highly essential to treat cancer properly. Nanotechnology provides new rays of hope for the effective treatment of cancer. Nanotechnology-based drug delivery carriers (NCs), such as nanoparticles, liposomes, dendrimers, polyplexes, and many more, offer treatment strategies due to their ability to target cancer cells. As these NCs target cancer cells, the exposure of other tissues to the drug is very less. Hence, these NCs exhibit fewer side effects in comparison with standard anti-cancer drugs. Here, we try to summarize a precise introduction of different NCs and their role in cancer therapy.
