Gels for cells: A new method to produce biocompatible polyglycerol microgel nanoparticles with controllable size (25–100 nm, see picture, top) and a readily functionalizable surface is developed. Fluorescence imaging shows clear evidence for particle uptake by cells through endocytotic pathways and localization of the particles in the perinuclear region.
