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

Georg Fantner, John McKinney, 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 ...

Characterization of Efficiency and Mechanisms of Cold Atmospheric Pressure Plasma Decontamination of Seeds for Sprout Production

Alexandra Waskow

The consumption of fresh fruit and vegetable products has strongly increased during the past few decades. However, inherent to all minimally processed products is the short shelf life, and the risk of foodborne diseases, which have been increasingly relate ...

Nanostructured surface topographies have an effect on bactericidal activity

Jürgen Brugger, Songmei Wu

Background Due to the increased emergence of antimicrobial resistance, alternatives to minimize the usage of antibiotics become attractive solutions. Biophysical manipulation of material surface topography to prevent bacterial adhesion is one promising app ...

Physics and applications of charged domain walls

Alexander Tagantsev, Tomas Sluka, Petr Yudin, Petr Bednyakov

The charged domain wall is an ultrathin (typically nanosized) interface between two domains; it carries bound charge owing to a change of normal component of spontaneous polarization on crossing the wall. In contrast to hetero-interfaces between different ...

Spatial organization of the somatosensory cortex revealed by osmFISH

Gioele La Manno

Global efforts to create a molecular census of the brain using single-cell transcriptomics are producing a large catalog of molecularly defined cell types. However, spatial information is lacking and new methods are needed to map a large number of cell typ ...

Perovskite/Perovskite/Silicon Monolithic Triple-Junction Solar Cells with a Fully Textured Design

Christophe Ballif, Quentin Thomas Jeangros, Florent Sahli, Arnaud Walter, Sylvain Nicolay, Björn Niesen, Jérémie Werner, Fan Fu

High efficiency triple-junction solar cells are currently made of III−V semiconductors using expensive deposition methods. Perovskite/perovskite/silicon monolithic triple-junction solar cells could be a lower-cost alternative as no epitaxial growth is requ ...

Interaction of silver nanoparticles with algae and fish cells: a side by side comparison

Kristin Schirmer, Laura Sigg, Renata Behra, Yang Yue, Xiaomei Li

Background: Silver nanoparticles (AgNP) are widely applied and can, upon use, be released into the aquatic environment. This raises concerns about potential impacts of AgNP on aquatic organisms. We here present a side by side comparison of the interaction ...

Grafted semiconductors on PE-films leading to bacterial inactivation: Synthesis, characterization and mechanism

César Pulgarin, Juan Kiwi, Sami Rtimi

This study reports the colloidal preparation FeOx, TiO2 and FeOx-TiO2 grafted on polyethylene (PE) films leading to bacterial inactivation. A fast bacterial inactivation was attained by the FeOx-TiO2 compared to the FeOx-PE film due to the interfacial char ...
