Isotropic reconstruction of 3D fluorescence microscopy images using convolutional neural networks

, 2017
Fluorescence microscopy images usually show severe anisotropy in axial versus lateral resolution. This hampers downstream processing, i.e. the automatic extraction of quantitative biological data.

Decoupling Size and Electronic Effects in Doped SrTiO3 Photocatalysts Through Surface Area–Normalized CO2 Hydrogenation Rates

Advanced Functional Materials, EarlyView.
Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.

Tiling light sheet selective plane illumination microscopy using discontinuous light sheets

Optics Express, 2019
Tiling light sheet selective plane illumination microscopy (TLS-SPIM) improves the 3D imaging ability of SPIM by using real-time optimized tiling light sheets. However, the imaging speed decreases and the raw image size increases due to the tiling process and additional camera exposures.

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

Advanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

RESOLFT Light-sheet Microscopy

, 2015
The concept of RESOLFT was introduced to break the resolution limit in fluorescence microscopy, which is set by the physical phenomenon of diffraction. It enables the separation of fluorophores inside a focal volume by driving reversible optical transitions between two discernible states. The family of reversibly switchable fluorescent proteins (RSFPs)

Light-sheet optimization for microscopy

SPIE Proceedings, 2016
Aberrations, scattering and absorption degrade the performance light-sheet fluorescence microscopes (LSFM). An adaptive optics system to correct for these artefacts and to optimize the light-sheet illumination is presented. This system allows a higher axial resolution to be recovered over the field-of-view of the detection objective.
