                Boltorn®H30 and Boltorn® H40 are hyperbranched aliphatic polyester polyolpolymers that because of their biocompatibility, biodegradabilityand a globular architecture with endocavities that can be used for ions orsmall molecules admission, have received much attention in designing of novelmaterials for biomedicine. 1                In this work, wepresent the surface characterization of Boltorn® H30 and Boltorn® H40 self-assembled onto highly oriented pyrolytic graphite (HOPG) byatomic force microscopy. The dependence of different factors as incubation time,concentration or temperature on the layer formation is analysed by means ofchanges in topography and phase images. 1.            Abandansari, H.
