Abstract
Nanoparticles have attracted considerable recent interest for diverse biomedical applications because of the unique properties of the nanomaterials. It is already known that one of the major advances in the relative application of nanoparticles is the recognition of the steric stabilization which can increase the particle stability in the biological environment and provide the opportunities of the application of nanoparticles in the development of drug delivery systems (DDSs) for achieving drug targeting and controlled drug release. To facilitate their use in such applications, the appropriate design of surface ligands on these nanoparticles is necessary. In view of these, functionalized nanoparticles through surface modification can be utilized to specifically interact with the target molecules on the cell membrane or intracellular ones. This review briefly presents self-assembled nanoparticles with molecules of therapeutic significance with two strategies. The first strategy attempts to improve the placement of the drugs using conjugating the appropriate ligands or adding targeting moieties to the DDS. The second strategy utilizes trigger-controlled drug-release, which restricts drug release at the targeted site to kill cancer cells by externally controlled mechanisms. Among external stimulations, conveniently light has attracted much interest because it, as an orthogonal external stimulus, gives spatiotemporal control of payload release.
