Active illumination and computational Methods for Temporal and Spectral Super-Resolution Microscopy

Christian Jaques

Light microscopy is a tool of paramount importance for biologists and has been constantly improved for the past four centuries. Despite many recent developments, microscopy techniques still require improvement, especially to reach better temporal and spect ...

Temporal resolution doubling in fluorescence light-sheet microscopy via a hue-encoded shutter and regularization

Michael Stefan Daniel Liebling, Christian Jaques

Studying dynamic biological processes, such as heart development and function in zebrafish embryos, often relies on multi-channel fluorescence labeling to distinguish multiple anatomical features, yet also demands high frame rates to capture rapid cell mot ...

Waveguide-PAINT offers an open platform for large field-of-view super-resolution imaging

Aleksandra Radenovic, Suliana Manley, Evgenii Glushkov, Anton Stroganov, Anna Archetti

Super-resolution microscopies based on the localization of single molecules have been widely adopted due to their demonstrated performance and their accessibility resulting from open software and simple hardware. The PAINT method for localization microscop ...

Thermal Drawing of Polymer Nano-composites: Fluid Dynamic Analysis and Application to Novel Functional Fibers

Alexis Gérald Page

The thermal drawing process is emerging as a versatile platform for the development of multimaterial fiber devices and advanced textiles for sensing, energy harvesting or medical applications, owing to the possibility to integrate insulators, conductors an ...

Dielectric-sphere-based microsystem for optical super-resolution imaging

Gergely Huszka

Well-established imaging techniques proved that features below the diffraction limit can be observed optically using so-called super-resolution microscopies, which overcome Abbe's resolution limit. In traditional far-field microscopy, the introduction of f ...

Orthogonal Tip-to-Tip Nanocapillary Alignment Allows for Easy Detection of Fluorescent Emitters in Femtomolar Concentrations

Aleksandra Radenovic, Michael Graf

Here we present the realization of a novel fluorescence detection method based on the electromigration of fluorescent molecules within a nanocapillary combined with the laser excitation through a platinum (Pt)-coated nanocapillary. By using the Pt nanocapi ...

Feasibility study on a novel daylighting system with embedded micro compound parabolic concentrators (CPCs)

Jean-Louis Scartezzini, Andreas Schueler, André Gabriel Kostro, Jing Gong

A novel glazing system consisting of a polymer layer with embedded micro compound parabolic concentrators (CPCs), which is attached to a glass pane of glazing, is proposed. It aims to reduce the energy consumption due to cooling in buildings, provide dayli ...

Scanning near-field optical microscopy with new probes and feedback modes

Anton Smirnov

Scanning Near-field Optical Microscopy (SNOM) technique enables to overcome Abbe diffraction limit of far-field optics as well as to obtain simultaneously optical and topographical images. While the optical resolution of the method is limited by the apertu ...

Spinning-disc confocal microscopy in the second near-infrared window (NIR-II)

Ardemis Anoush Boghossian, Alessandra Antonucci, Benjamin Paul Johanès Gabriel Lambert, Vitalijs Zubkovs

Fluorescence microscopy in the second near-infrared optical window (NIR-II, 1000–1350 nm) has become a technique of choice for non-invasive in vivo imaging. The deep penetration of NIR light in living tissue, as well as negligible tissue autofluorescence w ...

Super-resolution optical imaging: A comparison

Martinus Adela Maria Gijs, Gergely Huszka

Overcoming the classical diffraction limit in optical microscopy is known to be achievable by a variety of far-field and near-field microscopy techniques. More recently, so-called micro-object-based optical super-resolution microscopy techniques have emerg ...

Nanoscale Lithography and Thermometry with Thermal Scanning Probes

Samuel Tobias Howell

Thermal scanning probe lithography (t-SPL) is an advanced lithography technique in which a heated atomic force microscope tip locally modifies a sample material. Due to the nanometer-sized tip apex diameter, t-SPL enables patterning of sub-10 nm structures ...

Multimode fiber optical imaging using wavefront control

Nicolino Stasio

Optical microscopy enables us to observe at high resolution and with a large field of view objects otherwise invisible for the naked eye. This is why it is becoming a fundamental tool in biology and in diagnostics, where observation at cellular level can t ...

Black Lipid Membranes: Challenges in Simultaneous Quantitative Characterization by Electrophysiology and Fluorescence Microscopy

Esther Amstad

Horizontal black lipid membranes (BLMs) enable optical microscopy to be combined with the electrophysiological measurements for studying ion channels, peptide pores, and ionophores. However, a careful literature review reveals that simultaneous fluorescenc ...
