Twin-Photon Confocal Microscopy

open access: yes, 2010
A recently introduced two-channel confocal microscope with correlated detection promises up to 50% improvement in transverse spatial resolution [Simon, Sergienko, Optics Express {\bf 18}, 9765 (2010)] via the use of photon correlations.

Deep learning in computational microscopy [PDF]

open access: yes, 2019
We propose to use deep convolutional neural networks (DCNNs) to perform 2D and 3D computational imaging. Specifically, we investigate three different applications. We first try to solve the 3D inverse scattering problem based on learning a huge number of

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

One-step synthesis of Pt/a-CoOx core/shell nanocomposites

open access: yesApplied Microscopy, 2019
Herein, we synthesize a core/shell Pt/a-CoOx nanocomposite via one-step synthesis using a strong reaction agent of borane t-butylamine(BBA) at 200 °C. Transmission electron microscopy study shows that the morphology of nanocomposites is controlled by the

Double staining method for array tomography using scanning electron microscopy

open access: yesApplied Microscopy, 2020
Scanning electron microscopy (SEM) plays a central role in analyzing structures by imaging a large area of brain tissue at nanometer scales. A vast amount of data in the large area are required to study structural changes of cellular organelles in a ...

Towards nanoelectromechanical photothermal localization microscopy [PDF]

open access: yesarXiv, 2020
Single-molecule microscopy has become an indispensable tool for biochemical analysis. The capability of characterizing distinct properties of individual molecules without averaging has provided us with a different perspective for the existing scientific issues and phenomena.

The solution supramolecular structure of α2 → 8 polysialic acid suggests a structural cause for its low immunogenicity

open access: yesFEBS Letters, EarlyView.
α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

Next-generation fluorescent nucleic acids probes for microscopic analysis of intracellular nucleic acids

open access: yesApplied Microscopy, 2019
Fluorescence imaging of nucleic acids is a very important technique necessary to understand gene expression and the resulting changes in cell function. This mini-review focuses on sequence-specific fluorescence imaging of intracellular RNA and methylated

In-situ formation of co particles encapsulated by graphene layers

open access: yesApplied Microscopy, 2022
The process of encapsulating cobalt nanoparticles using a graphene layer is mainly direct pyrolysis. The encapsulation structure of hybrids prepared in this way improves the catalyst stability, which greatly reduces the leaching of non-metals and ...

Electron Microscopy [PDF]

open access: yes, 2012
Correlative light (LM) and transmission electron microscopic (TEM) analysis is useful, if ultrastructural details of cells need to be related to functional aspects which can only be examined at the LM level. The first protocol presented here introduces a relatively simple way of obtaining TEM images which, on the one hand, reveal ultrastructural ...
