The use of nanoparticulate pharmaceutical carriers to enhance the in vivo efficiency of many drugs well established itself over the past decade both in pharmaceutical research and clinical setting. The current level of engineering pharmaceutical nanocarriers in some cases allows for drug delivery systems (DDS) to demonstrate a combination of some desired properties. However, looking into the future of the field of drug delivery, we have to think about the development of the next generation of pharmaceutical nanocarriers combining different properties and allowing for multiple functions.
