Real-space identification of intermolecular bonding with atomic force microscopy.

We report a real-space visualization of the formation of hydrogen bonding in 8-hydroxyquinoline (8-hq) molecular assemblies on a Cu(111) substrate, using noncontact atomic force microscopy (NC-AFM). The atomically resolved molecular structures enable a precise determination of the characteristics of hydrogen bonding networks, including the bonding sites, orientations, and lengths. The observati...

Probing Intermolecular Forces and Potentials with Magnetic Feedback Chemical Force Microscopy

Magnetic feedback chemical force microscopy (MF-CFM) was used to map the complete force profile between hydroxyland carboxyl-terminated self-assembled monolayers (SAMs) in aqueous solution. The snap-to-contact and snap-out instabilities intrinsic to force-displacement measurements made with weak spring constant cantilevers were eliminated by using a cantilever with an attached magnetic particle...

Chemical Force Microscopy Nanoscale Probing of Fundamental Chemical Interactions

Intermolecular forces impact a wide spectrum of problems in condensed phases: from molecular recognition, self-assembly, and protein folding at the molecular and nanometer scale, to interfacial fracture, friction, and lubrication at a macroscopic length scale. Understanding these phenomena, regardless of the length scale, requires fundamental knowledge of the magnitude and range of underlying w...

Intermolecular contrast in atomic force microscopy images without intermolecular bonds.

Intermolecular features in atomic force microscopy images of organic molecules have been ascribed to intermolecular bonds. A recent theoretical study [P. Hapala et al., Phys. Rev. B 90, 085421 (2014)] showed that these features can also be explained by the flexibility of molecule-terminated tips. We probe this effect by carrying out atomic force microscopy experiments on a model system that con...

Probing single biomolecules with atomic force microscopy.

During the last years, atomic force microscopy (AFM) has developed from a microscopy tool for solid-state surface science toward a method employed in many scientific disciplines, such as biology, for investigating individual molecules on a nanometer scale. This article describes the current status of the imaging possibilities of AFM on RNA, IgG, and gold-labeled cell adhesion proteoglycans, as ...
