Sources and seasonality of fluorescent aerosols in the Arctic

Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Nora Bergner, Alireza Moallemi

Aerosol‐cloud interactions play an important role in the Arctic climate but remain poorly understood. Ice nucleating particles (INPs) contribute to the formation of ice crystals at temperatures above ‐38 °C in mixed phase clouds, which are predominant in t ...

Super-resolution optical imaging: A comparison

Martinus 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 ...

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 ...

Simultaneous temporal superresolution and denoising for cardiac fluorescence microscopy

Michael Stefan Daniel Liebling

Due to low light emission of fluorescent samples, live fluorescence microscopy imposes a tradeoff between spatiotemporal resolution and signal-to-noise ratio. This can result in images and videos containing motion blur or Poisson-type shot noise, depending ...

Second harmonic nanoparticles in imaging applications

Demetri Psaltis, Ioannis Papadopoulos, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Jae-Woo Choi, Xin Yang

Nanocrystals with second harmonic response is a new class of nonlinear optical nanoprobes with dramatically different properties from fluorescent agents. Compared with two-photon fluorescence, second harmonic generation is an ultrafast, lossless, and coher ...

Fast Single-Photon Avalanche Diode Arrays for Laser Raman Spectroscopy

Edoardo Charbon

We incorporate newly developed solid-state detector technology into time-resolved laser Raman spectroscopy, demonstrating the ability to distinguish spectra from Raman and fluorescence processes. As a proof of concept, we show fluorescence rejection on hig ...

Microfabricated Multimode Bio-interface with High Density Microelectrode Array and Photonic Detectors

Mohssen Moridi

Presently, the cells' electrical activity is measured either by extracellular microelectrode array (MEA) or by microscopic fluorescence imaging methods. The MEA is a non-invasive in vitro technique which allows long-term recording at multicellular level wh ...

Towards in vivo small animal imaging

Theo Lasser, Michael Friedrich, Rainer Leitgeb, Anne Grapin-Botton, Martin Villiger, Joan Goulley

Fourier domain Optical coherence microscopy (FDOCM) offers excellent sensitivity and high axial resolution to image the structure of biological tissue. The depth information is extracted in parallel and allows very high volume acquisition rates. An illumin ...

Manipulation of magnetic microparticles in liquid phases for on-chip biomedical analysis methods

Ulrike Lehmann

Magnetic microparticles and their application in bioanalytical microfluidic systems have been steadily gaining interest in recent years. This progress is fueled by the comparatively large and long range magnetic forces that can be obtained independently of ...

Extended focus Fourier domain optical coherence microscopy assists developmental biology

Theo Lasser, Cathrin Brisken, Rainer Leitgeb

We present a novel detection scheme for Fourier domain optical coherence microscopy (FDOCM). A Bessel-like interference pattern with a strong central lobe was created with an axicon lens. This pattern was then imaged by a telescopic system into the sample ...
