Brain cancer diagnosis and therapy with nanoplatforms

Abstract

Treatment of brain cancer remains a challenge despite recent improvements in surgery and multimodal adjuvant therapy. Drug therapies of brain cancer have been particularly inefficient, due to the blood-brain barrier and the non-specificity of the potentially toxic drugs. The nanoparticle has emerged as a potential vector for brain delivery, able to overcome the problems of current strategies. Moreover, multi-functionality can be engineered into a single nanoplatform so that it can provide tumor-specific detection, treatment, and follow-up monitoring. Such multitasking is not possible with conventional technologies. This review describes recent advances in nanoparticle-based detection and therapy of brain cancer. The advantages of nanoparticle-based delivery and the types of nanoparticle systems under investigation are described, as well as their applications.
