The Clinical translation of Organic Nanomaterials for Cancer Therapy: A Focus on Polymeric Nanoparticles, Micelles, Liposomes and Exosomes

The application of nanotechnology in the medical field is called nanomedicine. Nowadays, this new branch of science is a point of interest for many investigators due to the important advances in which we assisted in the lasts decades, in particular for cancer treatment. Cancer nanomedicine has been applied in different fields such as drug delivery, nanoformulation and nanoanalytical contrast reagents. The application of nanotechnology to pharmaceutical science allowed to build up nanosystems based on at least two stage vectors (drug/nanomaterial), which often shown a better pharmacokinetics (PK), bioavailability and biodistribution. As result of these advantages, the nanomaterials accumulate passively in the tumor (enhanced permeability and retention, EPR) decreasing side effects of free drug. In the last decades, many new drug formulations have been translated from the bench to the bedside. In this review, we describe the main drug nanoformulations based on different types of organic nanoparticles (NPs), the advantages that the new formulations have over to their free drug counterparts and how nanodrugs have improved the clinical care
