Photothermal Off-Resonance Tapping for Rapid and Gentle Atomic Force Imaging of Live Cells

John McKinney, Georg Fantner, Adrian Pascal Nievergelt, Haig Alexander Eskandarian, Charlène Cécile Geneviève Brillard

Imaging living cells by atomic force microscopy (AFM) promises not only high-resolution topographical data, but additionally, mechanical contrast, both of which are not obtainable with other microscopy techniques. Such imaging is however challenging, as ce ...

An electron acceptor molecule in a nanomesh: F(4)TCNQ on h-BN/Rh(111)

Silvan Dino Marcos Roth, Huanyao Cun

The adsorption of molecules on surfaces affects the surface dipole and thus changes in the work function may be expected. The effect in change of work function is particularly strong if charge between substrate and adsorbate is involved. Here we report the ...

DNA-protein interactions explored by atomic force microscopy

Giovanni Dietler, Sandor Kasas

DNA-protein interactions play an important role in all living organisms on Earth. The advent of atomic force microscopy permitted for the first time to follow and to characterize interaction forces between these two molecular species. After a short descrip ...

Scanning tunneling microscopy on large bio-molecular systems on surfaces

Sebastian Koslowski

The ever growing demand for the development of new technologies and materials has led to extensive studies inspired by biological functional complexes. Peptides with their outstanding ability to efficiently self-assemble can express a broad spectrum of int ...

AlN grown on Si(111) by ammonia-molecular beam epitaxy in the 900-1200 degrees C temperature range

Denis Martin, Nicolas Grandjean, Sebastian Pascal Tamariz Kaufmann

We present a comprehensive study of AlN growth on Si(111) substrate by gas source molecular beam epitaxy with ammonia as nitrogen precursor in the high temperature range. We first demonstrate that the observation of the silicon 7 x 7 surface reconstruction ...

Synchronic coupling of Cu2O(p)/CuO(n) semiconductors leading to Norfloxacin degradation under visible light: Kinetics, mechanism and film surface properties

Michaël Bensimon, Juan Kiwi, César Pulgarin, Sami Rtimi, Gcina Mamba

The study presents the first evidence for Norfoxacin photodegradation by uniform, adhesive and robust CuOx-polystyrene (CuOx-PES) films under visible light. Repetitive Norfloxacin degradation was attained on CuOx-PES films activated by visible light. The s ...

Study on the bio-functionalization of memristive nanowires for optimum memristive biosensors

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Ioulia Tzouvadaki

Semiconductor nanowires are emerging as promising building blocks for biosensors enabling direct electrical detection of various biomolecules. In this framework, two-terminal Schottky-barrier silicon (Si) nanowire arrays that exhibit memristive electrical ...

Surface Structure and Chemistry of Alkanethiols on Au(100)-(1 x 1) Substrates

Klaus Kern

The surface structure of self-assembled monolayers of hexanethiolate (HT) on the Au(100)-(1 x 1) surface has been studied by density functional theory (DFT) calculations and their results compared to scanning tunneling microscopy (STM) and X-ray photoelect ...
