Biosensor-aided isolation of anaerobic arsenic-methylating bacteria from soil

Rizlan Bernier-Latmani, Karin Lederballe Meibom, Hugo Sallet, Nicolas Louis Maurice Jacquemin

Microbial methylation of arsenic impacts both the toxicity and fate of this environmental contaminant, and is an important component of its biogeochemical cycle. This transformation occurs in flooded paddy fields where soil microorganisms can produce dimet ...

An Optical Fiber-Based Nanomotion Sensor for Rapid Antibiotic and Antifungal Susceptibility Tests

Giovanni Dietler, Sandor Kasas, Serguei Sekatski, Jiangtao Zhou, María Inés Villalba, Leonardo Venturelli, Anne-Céline Verenna Kohler

The emergence of antibiotic and antifungal resistant microorganisms represents nowadays a major public health issue that might push humanity into a post-antibiotic/antifungal era. One of the approaches to avoid such a catastrophe is to advance rapid antibi ...

Enhancing spatial resolution in MÖNCH for electron microscopy via deep learning

Benjamin Bejar Haro, Luis Felipe Barba Flores, Carl Pierre Jacques Remlinger

However, their use in imaging applications has been limited by their relatively large pixel size (≥ 55 μm) and high-energy (>80 keV) electrons scattering over multiple pixels in the sensor layer. To realize the full potential of fast, radiation-hard HPDs a ...

Antimicrobial susceptibility testing with integrated photonic crystal optical tweezers

Nicolas Villa

The abusive use of antimicrobial drugs during the last eighty years has favoured the natural selection of resistant pathogens able to neutralise drugs efficiently. Nowadays, antimicrobial resistance contributes to millions of deaths yearly, threatens the e ...

Periodogram-Based Detection of Unknown Frequencies in Time-Resolved Scanning Transmission X-ray Microscopy

Joe Martin Bailey

Pump-probe time-resolved imaging is a powerful technique that enables the investigation of dynamical processes. Signal-to-noise and sampling rate restrictions normally require that cycles of an excitation are repeated many times with the final signal recon ...

Extremely confined gap plasmon modes: when nonlocality matters

Sergejs Boroviks

Historically, the field of plasmonics has been relying on the framework of classical electrodynamics, with the local-response approximation of material response being applied even when dealing with nanoscale metallic structures. However, when the confineme ...

Toward Super Temporal Resolution by Suppression of Mixing Effects of Electrons

Edoardo Charbon

The theoretical temporal resolution limit of silicon (Si) image sensors is 11.1 ps. The super temporal resolution (STR) is defined as a frame interval less than this limit. The temporal resolution of burst image sensors is significantly affected by ``mixin ...

Super-resolved Optical Mapping of Reactive Sulfur-Vacancies in Two-Dimensional Transition Metal Dichalcogenides

Aleksandra Radenovic, Andras Kis, Magalí Alejandra Lingenfelder, Martina Lihter, Michal Daniel Macha, Zhenyu Wang, Yanfei Zhao, Jean Camille Benjamin Comtet, Karla Banjac, Miao Zhang, Tzu-Heng Chen, Jing Zhang

Transition metal dichalcogenides (TMDs) represent a class of semiconducting two-dimensional (2D) materials with exciting properties. In particular, defects in 2D-TMDs and their molecular interactions with the environment can crucially affect their physical ...

Self-assembly of nanostructured glass metasurfaces via templated fluid instabilities

Hatice Altug, Fabien Sorin, Alexis Gérald Page, Wei Yan, Filiz Yesilköy, Yunpeng Qu, Dang Tùng Nguyen, Louis Marie Philippe Martin-Monier, Arthur Le Bris

Modern devices require the tuning of the size, shape and spatial arrangement of nano-objects and their assemblies with nanometre-scale precision, over large-area and sometimes soft substrates. Such stringent requirements are beyond the reach of conventiona ...
