Kraftinduzierte Sekundärstrukturänderungen in einzelnen Molekülen
… Technik der auf dem Kraftmikroskop basierenden Einzelmolekül-Kraftspektroskopie auf zwei spezielle Systeme angewendet: Poly(ethylen Glycol) (PEG) und das Membranprotein Bakteriorhodopsin. Im Vordergrund stand dabei die Analyse der mechanischen Stabilität von Sekundärstrukturen. PEG ist aufgrund …

Single-Molecule Measurements of Complex Molecular Interactions in Membrane Proteins using Atomic Force Microscopy
Single-molecule force spectroscopy (SMFS) with atomic force microscope (AFM) has advanced our knowledge of the mechanical aspects of biological processes, and helped us take big strides in the hitherto unexplored areas of protein (un)folding. One such virgin land is that of membrane proteins, where …

Molecular assemblies observed by atomic force microscopy
We use time-lapse AFM to visualize collagen fibrils self-assembly. A solution of acid-solubilized collagen was injected into the AFM fluid cell and fibril formation was observed in vitro. Single fibrils continuously grew and fused with each other until the supporting surface was completely covered …
