Atomic Force Microscopy News and Research

RSS

Atomic force microscopy is a type of scanning probe microscopy used to image the surface of a substance, but at an atomic level. It can map the surface structure of different substances to understand how different structures interact with each other. This is done using a cantilever, which is similar to a vinyl record needle.

Phase separation of lipid membranes analyzed with high-resolution secondary ion mass spectrometry

Understanding the chemical composition and organization of cell membranes - what components reside next to each other, how many of each there are and how they respond to their environment - may reveal the secret lives of cells in both health and disease.

Startling discovery about the properties of human bone

The scientists describe their results - finding a sort of "glue" in human bone - in the cover story of the August issue of the international scientific journal, Nature Materials. The article was published on-line on July 17. It describes how healthy bone resists fracture and how unhealthy bone fractures at the molecular level.
