Book Description
Atomic force microscopy (AFM) is an amazing technique that allies a versatile methodology (that allows measurement of samples in liquid, vacuum or air) to imaging with unprecedented resolution. But it goes one step further than conventional microscopic techniques; it allows us to make measurements of magnetic, electrical or mechanical properties of the widest possible range of samples, with nanometre resolution. This book will demystify AFM for the reader, making it easy to understand, and to use. It is written by authors who together have more than 30 years experience in the design, construction, and use of AFMs and will explain why the microscopes are made the way they are, how they should be used, what data they can produce, and what can be done with the data. Illustrative examples from the physical sciences, materials science, life sciences, nanotechnology and industry demonstrate the different capabilities of the technique.

Book Description
Imaging and Manipulation of Adsorbates using Dynamic Force Microscopy provides an overview of the latest developments in dynamic force microscopy (DFM) of atoms, molecules, and nanoparticles adsorbed on solid surfaces. Significant advances in the capabilities of this technique have been made in the last decade and this book represents a timely snapshot of the major research themes in the field, with a particular focus on the manipulation of matter at the atomic and (sub)molecular levels. This edited volume will be of keen interest to researchers active in nanoscience and its various sub-fields including, in particular, scanning probe microscopy. This book expands on the previous volumes in the series Advances in Atom and Single Molecule Machines. DFM is an exceptionally powerful tool for the imaging and probing of adsorbates on insulators and is now a component of the type of multiprobe interconnection systems described in Vol. 1 of the series. DFM can also be used to translate atoms and molecules in the context of the fabrication of the type of logic gates described in Vol. 2. When used in conjunction with STM, DFM also enables a detailed comparison of the chemical ‘architecture’ of a molecule with the spatial distribution of its orbital density, as described in Vol. 3. In this book readers will gain key insights into the current capabilities, and future potential, of dynamic force microscopy.

Book Description
Since the original publication of Noncontact Atomic Force Microscopy in 2002, the noncontact atomic force microscope (NC-AFM) has achieved remarkable progress. This second treatment deals with the following outstanding recent results obtained with atomic resolution since then: force spectroscopy and mapping with atomic resolution; tuning fork; atomic manipulation; magnetic exchange force microscopy; atomic and molecular imaging in liquids; and other new technologies. These results and technologies are now helping evolve NC-AFM toward practical tools for characterization and manipulation of individual atoms/molecules and nanostructures with atomic/subatomic resolution. Therefore, the book exemplifies how NC-AFM has become a crucial tool for the expanding fields of nanoscience and nanotechnology.

Book Description
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 the advent of AFM has not only helped to visualize the difficult to crystallize membrane proteins at the single-molecule level, but also given a new perspective in the understanding of the interplay of molecular interactions involved in the construction of these molecules. My PhD work was tightly focused on exploiting this sensitive technique to decipher the intra- and intermolecular interactions in membrane proteins, using bacteriorhodopsin and bovine rhodopsin as model systems. Using single-molecule unfolding measurements on different bacteriorhodopsin oligomeric assemblies - trimeric, dimeric and monomeric - it was possible to elucidate the contribution of intra- and interhelical interactions in single bacteriorhodopsin molecules. Besides, intriguing insights were obtained into the organization of bacteriorhodopsin as trimers, as deduced from the unfolding pathways of the proteins from different assemblies. Though the unfolding pathways of bacteriorhodopsin from all the assemblies remained the same, the different occurrence probability of these pathways suggested a kinetic stabilization of bacteriorhodopsin from a trimer compared to that existing as a monomer. Unraveling the knot of a complex G-protein coupled receptor, rhodopsin, showed the existence of two structural states, a native, functional state, and a non-native, non-functional state, corresponding to the presence or absence of a highly conserved disulfide bridge, respectively. The molecular interactions in absence of the native disulfide bridge mapped onto the three-dimensional structure of native rhodopsin gave insights into the molecular origin of the neurodegenerative disease retinitis pigmentosa.
