A detailed structural analysis of the surface supported self-assembly of terphenyl-4,4′′-dicarbonitrile molecules (NC−Ph3−CN) linked by Co adatoms on Ag(111) reveals different surface patterns depending on the constraints applied to the system. Without con ...
A scanning electrochemical microscopy (SECM) protein detection methodology has been developed based on the tagging of free cysteines and other nucleophiles in proteins and peptides by benzoquinone. The tagged proteins are detected by the mediated reduction ...
The general idea of Nanotechnology is not new – it has been studied since Nobel laureate Richard Feynman outlined the idea in a speech in 1959 – but it's only recently that the progress carried out in the various fields of material, optic, physic and engin ...
A combined atomic force and scanning electrochemical microscope probe is presented. The probe is electrically insulated except at the very apex of the tip, which has a radius of curvature in the range of 10-15 nm. Steady-state cyclic voltammetry measuremen ...
Due to the importance of scanning tunneling microscopy for atomic scale research the anomalously high corrugation values on close packed metal surfaces have been the subject of debate and extensive theoretical work in the past two decades. To date it remai ...
The growth of rubrene (C42H28, 5,6,11,12-tetraphenylnaphthacene) multilayer islands up to a thickness of six layers on a Au(111) surface has been investigated by scanning tunneling microscopy. The molecules self-organize in parallel twin rows, forming mirr ...
In this work the development of a low-temperature scanning probe microscope and the investigation of thin insulating films at the atomic limit is presented. The scanning probe microscope has been designed in a modular way to provide large flexibility for t ...
This paper describes the characterization and application of electrically insulated conductive tips mounted on a cantilever for use in an atomic force microscope and operated in liquid. These multifunctional probes were microfabricated and designed for mea ...
An efficient strategy for visualizing human fingerprints on a poly(vinyldene difluoride) membrane (PVDF) by sanning electrochemical microscopy (SECM) has been developed. Compared to a classical ink fingerprint image, here the ink is replaced by an aqueous ...
Scanning electrochemical microscopy (SECM) has developed into an excellent and versatile technique to image heterogeneous chemical reactivities on a surface. Therefore SECM applications cover a wide range of different fields such as biology and forensic sc ...
