Emerging Engineered Nanoweapons for Tumors

Abstract

Cancer is a type of disease characterized by abnormal growth of cells which tend to proliferate in uncontrolled manner. It occurs at molecular level when genes undergo genetic alterations. The malignant growth of tumor cells results in non-functioning of the concerned organ. Over the years, cancer targeting technique has greatly improved by new approaches based on nanotechnology. Nanotechnology is helpful in development of new therapies against cancer. Nanotechnology is a boon for diagnosis, treatment and prevention of cancer disease. The most challenging task, i.e., targeting of the desired drug to the tumor tissues is a major area of concern today. Several nanobiotechnologies mostly based on nanoparticles have been used to facilitate drug delivery in cancer. There are various tools in the field of nanotechnology which can be used to treat cancer, such as gold nanoparticles, nanofibers, nanopores, nanoshells and nanotubes. Gold and nanotechnology are in the age of innovation. Nanotechnology-based cancer treatment approaches provide localized targeted therapies that aim to enhance efficacy, reduce side effects and improve patient’s life. The basic approach of this review is to discuss the new defining features of cancer technology with the help of nanotechnology, by which we can evade cancerous cells
