Nano based Drug Delivery System for Cancer Therapy: A Next Generation Theranostics

Cancer is considered as one of the foremost cause of illness and death with very complex pathophysiology even though prominent advancement has been made on innovative tumor treatments. Therapeutic properties and the global survival rate are still disappointing for the patients with cancer. There is a shortfall in the capabilities of these cancer therapies, some novel strategies are developed to provide better treatment therapies to improve their quality of life and also aids in reducing the number of deaths. Amongst the cardinal phases towards ensuring ideal cancer management is early diagnosis and targeted drug delivery of anti-tumor to decrease its toxicities. Recently the progress of nanotechnology as novel therapeutics, have advanced and trialed to overwhelm numerous limitations of previously available drug delivery systems for cancer treatment. Nanobased therapeutics has provided the chance to directly contact the tumorous cells selectively with improved drug localization, cellular application as well as providing targeted drug delivery eluding the interaction with the healthy cells. In this review, we summarize about various novel nanomaterials as anti-tumour drug delivery carriers for cancer treatment; also provide insight into the superlative necessities of nanotechnology in cancer therapy and its challenges in targeted drug delivery
