This study on novel drug delivery systems (NDDS) in cancer therapy comprises study of technologies such as embolization devices, liquid embolics and nanoparticles that offer unique approaches in cancer remedy. Several embolic agents are used by interventional radiologists for the selective occlusion of arteries supplying blood to tumors. The selection of an embolic agent depends on various factors including size of the vessel to be embolized, desired clinical outcome, duration of the vessel to be occluded, and also the intrinsic properties and behavior of the embolic agent. Nanoparticles as drug delivery systems have emerged as a promising technology to treat patients suffering from various types of cancer. Owing to their small size, nanoparticles exhibit unique physicochemical and biological properties, and thus help in overcoming several limitations such as poor bio-distribution, non-specific drug delivery, low therapeutic indices, and lack of water solubility which are mostly associated with conventional drug delivery.
