Nanoparticle interactions on a cellular scale

Nanoobjects are distinguished from other materials by their nanoscale size. The special physico-chemical properties of nanoobjects attributed to size-effects are the basis for their high application potential. Some of these properties are considered to be the basis for biologically relevant effects of nanoobjects. These are promoted by a) specific entry pathways and distribution within the body and tissues, b) uptake into single cells and specific intracellular distribution, and c) a high chemical reactivity, influencing dissolution, adsorption patterns and kinetics, or agglomeration. To take this even further,…
