Abstract

Conventional chemotherapy drugs show lack of specificity, including reduced activity on cancer treatment with higher toxicity to normal cells and develop resistance after prolonged period of administration. Recently, to nullify all adverse effects of cancer chemotherapy nanometer sized carriers came into role for total cure. The advanced research community is focused on smart drug delivery system owing to their vivid biomedical and pharmaceutical applications. This article will provide an in-depth discussion on development of smart nanosized carriers for tumors targeting and highlight important role of QDs in highly challenging area of nanotechnology.
