Three-dimensional skin models as tools for transdermal drug delivery: challenges and limitations.

abstract：INTRODUCTION:In the therapy of clinical diseases such as cancer, it is important to deliver drugs directly to tumor sites in order to maximize local drug concentration and reduce side effects. This objective may be realized by using 'smart' nanoparticles (NPs) as drug delivery systems, because they enable dramatic conf...
