Nanomaterials can enhance the delivery and treatment efficiency of anti-cancer drugs, and the mechanisms of the tumor-reducing activity of nanomaterials with cancer drug have been investigated. The task for drug to reach pathological areas has facilitated rapid advances in nanomedicine. Herein, we summarize promising findings with respect to cancer therapeutics based on nano-drug delivery vectors. Relatively high toxicity of uncoated nanoparticles restricts the use of these materials in humans. In order to reduce toxicity, many approaches have focused on the encapsulation of nanoparticles with biocompatible materials. Efficient delivery systems have been developed that utilized nanoparticles loaded with high dose of cancer drug in the presence of bilayer molecules. Well-established nanotechnologies have been designed for drug delivery with specific bonding. Surface-modified nanoparticles as vehicles for drug delivery system that contains multiple nano-components, each specially designed to achieve aimed task for the emerging application delivery of therapeutics. Drug-coated polymer nanoparticles could efficiently increase the intracellular accumulation of anti-cancer drugs. This review also introduces the nanomaterials with drug on the induction of apoptosis in cancer cells in vitro and in vivo. Direct interactions between the particles and cellular molecules to cause adverse biological responses are also discussed.
