Drug delivery systems based on nanoparticles and related nanostructures

A new approach to drug design based on nanoparticles and related nanostructures for effective drug delivery, is of great importance in future medical treatment, especially for cancer therapy. Nanomaterials hold tremendous potential for increasing the efficiency of drug delivery, with a high degree of biocompatibility. Additionally, for biomedical applications, they must be biodegradable, have prolonged circulation half-life, not tend to aggregate or cause an inflammatory response in the body and to be cost-effective. The efficacy of such structures is highly dependent on their chemical properties as well as on shape, charge, size, surface modifications and loading method. Here we focused on the potential of using different kinds of nanoparticles and similar nanostructures loaded with various drugs in order to achieve specific targeting and controlled drug release. Thereby, computational modeling on NPs-based drug delivery could help in providing a better understanding of all parts of the delivery system. This review emphasizes recent advances in the usage of various types of nanoparticles and similar nanostructures for drug delivery, aiming to provide a critical review of less toxic and more effective treatment.
