Biological interfaces

Study of the interaction of biological objects on different surfaces such as DNA/liposomes/proteins/cells/virions on LGM’s nanostructured surfaces or mica surfaces. Intermittent contact mode in liquid environment allows us to scan extremely soft objects weakly adsorbed to the surface. In this way it is possible to operate applying probe-surface forces in the pico Newton range.
