Journal ArticleDOI
Atomic-Scale Distribution of Water Molecules at the Mica-Water Interface Visualized by Three-Dimensional Scanning Force Microscopy
TL;DR: This 3D-SFM image obtained at a mica-water interface visualizes 3D distributions of adsorbed water molecules above the center of hexagonal cavities and the laterally distributed hydration layer.
Journal ArticleDOI
Three-dimensional quantitative force maps in liquid with 10 piconewton, angstrom and sub-minute resolutions
TL;DR: A bimodal force microscopy method is developed to map the three-dimensional force fields and their time-evolution on a variety of solid-water interfaces and records the existence and evolution of nanoscale perturbations involving thousands of water molecules of the protein-liquid interface.
Journal ArticleDOI
Spatial distribution of lipid headgroups and water molecules at membrane/water interfaces visualized by three-dimensional scanning force microscopy.
TL;DR: 3D-SFM is demonstrated to be capable of visualizing averaged 3D distribution of fluctuating surface structures as well as that of mobile water at interfaces between biological systems and water.
Journal ArticleDOI
Atomic-resolution imaging in liquid by frequency modulation atomic force microscopy using small cantilevers with megahertz-order resonance frequencies
TL;DR: While a small carbon tip formed by electron beam deposition (EBD) is desirable for small cantilevers, it is found that an EBD tip is not suitable for atomic-scale applications due to the weak tip-sample interaction, and it is shown that the tip- sample interaction can be greatly enhanced by coating the tip with Si.
Journal ArticleDOI
Nanoscale potential measurements in liquid by frequency modulation atomic force microscopy
TL;DR: A method for local potential measurements in liquid using frequency modulation atomic force microscopy, which calculates local potential from the first and second harmonic vibrations of a cantilever induced by applying an ac bias voltage between a tip and a sample.
