SmartLipids—The Third Generation of Solid Submicron Lipid Particles for Dermal Delivery of Actives

Abstract

Nanotechnology deals with particles or structures being in the nanodimension, which means from the technical definition below 1 µm. The size range is from a few nm to below 1000 nm (≙1 µm). There are two groups of particles: nanoparticles according to the legal definition being below 100 nm, and the particles between 100 and 1000 nm which are called submicron particles for better differentiation.
