Nanobubbles on solid surface imaged by atomic force microscopy
Gas bubbles of nanometer size were produced on atomically flat solid surfaces and imaged by atomic force microscopy (AFM) in tapping mode in water. In AFM images, nanobubbles appeared like blight
Electrochemically controlled formation and growth of hydrogen nanobubbles.
The observation of electrochemically controlled formation and growth of hydrogen nanobubbles on bare highly oriented pyrolytic graphite (HOPG) surface via in-situ tapping mode atomic force microscopy (TMAFM) is reported.

This paper shows the discovery of an amyloid structure, termed “amyloid-like nanosheet,” formed by a key amyloids-forming segment of Alzheimer’s Aβ, and proposes a structural model for the nanos sheet that is formed by stacking theAmyloid fibril spines perpendicular to the fibrillar axis.
Adsorption of double-stranded DNA to graphene oxide preventing enzymatic digestion.
It is demonstrated that dsDNA can bind to GO forming complexes (dsDNA/GO) in the presence of certain salts, which protects ds DNA from being enzymatically digested, and it is found that a nonionic surfactant can block the formation of dsDN/GO complexes, so that the enzymatic digestion of dSDNA is restored.
Epitaxial growth of peptide nanofilaments on inorganic surfaces: effects of interfacial hydrophobicity/hydrophilicity.
This work compares the self-assembly behavior of the GAV-9 onhydrophilicmica andhydrophobicHOPG(highlyorderedpyrolyticgraphite) surfaces byinsituatomicforce microscopy (AFM) to investigate how interfacialhydrophobicity/hydrophilicity influences the epitaxialgrowth ofpeptidenanofilaments.
Nanobubbles influence on BSA adsorption on mica surface
Nanobubbles have been shown to exist at liquid/solid interfaces and have become the focus of research in varied interfacial processes. In the present work, bovine serum albumin (BSA) adsorbed on mica
Mechanical manipulation assisted self-assembly to achieve defect repair and guided epitaxial growth of individual peptide nanofilaments.
Using a unique mechanical manipulation method based on atomic force microscopy, this work is able to introduce mechanical stimuli to generate active ends at designated positions on an existing peptide nanofilament previously formed, and defects in the filament were removed and self-repairing occurred when the active ends extended along the direction of the supporting lattice, resulting in the closure of the broken filament.
A comparative study on the self‐assembly of an amyloid‐like peptide at water–solid interfaces and in bulk solutions
It was found that, when dissolved in bulk solutions, Pep11 formed into β‐sheet structures and assembled into long filaments in several hours, as revealed by Thioflavin T fluorescence and transmission electron microscope morphology characterization, respectively.
Positioning scission of single DNA molecules with nonspecific endonuclease based on nanomanipulation.
DNase I, a well-known and widely used nonspecific endonuclease, digested DNA at controlled sites by using an approach termed combined-dynamic dip-pen nanolithography (CDDPN).
