title: Microparticles and nanoparticles for drug delivery.
abstract: Particulate drug delivery systems have become important in experimental pharmaceutics and clinical medicine. The distinction is often made between micro- and nanoparticles, being particles with dimensions best described in micrometers and nanometers respectively. That size difference entails real differences at many levels, from formulation to in vivo usage. Here I will discuss those differences and provide examples of applications, for local and systemic drug delivery. I will outline a number of challenges of interest in particulate drug delivery.
