Protocol for live imaging of intracellular nanoscale structures using atomic force microscopy with nanoneedle probes

Atomic force microscopy (AFM) is capable of nanoscale imaging but has so far only been used on cell surfaces when applied to a living cell. Here, we describe a step-by-step protocol for nanoendoscopy-AFM, which enables the imaging of nanoscale structures i ...

Stain-free identification of cell nuclei using tomographic phase microscopy in flow cytometry

Demetri Psaltis, Joowon Lim, Daniele Pirone

The accurate identification of the three-dimensional quantitative shape of a cell nucleus is now possible without fluorescent staining by applying computational segmentation to refractive index tomograms recorded in the flow cytometry mode. ...

Using flow cytometry and light-induced fluorescence to characterize the variability and characteristics of bioaerosols in springtime in Metro Atlanta, Georgia

Athanasios Nenes

The abundance and speciation of primary biological aerosol particles (PBAP) is important for understanding their impacts on human health, cloud formation, and ecosystems. Towards this, we have developed a protocol for quantifying PBAP collected from large ...

Design and Synthesis of Gatekeeper Coated Dendritic Silica/Titania Mesoporous Nanoparticles with Sustained and Controlled Drug Release Properties for Targeted Synergetic Chemo-Sonodynamic Therapy

Saba Rezakhani, Samira Malekmohammadi

New dendritic silica/titania mesoporous nanoparticles (DSTNs) loaded with curcumin (CUR) were synthesized and coated with polyethylenimine-folic acid groups (PEI-FA) for an ultrasound (US)-triggered drug release and combined chemo-sonodynamic therapy. The ...

Microfluidic-based immunohistochemistry for breast cancer diagnosis: a comparative clinical study

Martinus Gijs, Diego Gabriel Dupouy, Saska Brajkovic, Fabio Aimi

Breast cancer is a highly heterogeneous disease. The efficacy of tailored therapeutic strategies relies on the precise detection of diagnostic biomarkers by immunohistochemistry (IHC). Therefore, considering the increasing incidence of breast cancer cases, ...

A Cell Atlas for the Mouse Brain

Henry Markram, Daniel Keller, Marc-Oliver Gewaltig

Despite vast numbers of studies of stained cells in the mouse brain, no current brain atlas provides region-by-region neuron counts. In fact, neuron numbers are only available for about 4% of brain of regions and estimates often vary by as much as 3-fold. ...

Scalable Unsupervised Domain Adaptation for Electron Microscopy

Pascal Fua, Mathieu Salzmann, Carlos Joaquin Becker, Róger Bermúdez Chacón

While Machine Learning algorithms are key to automating organelle segmentation in large EM stacks, they require annotated data, which is hard to come by in sufficient quantities. Furthermore, images acquired from one part of the brain are not always repres ...

Influence of DNA Binding Dyes on Bare DNA Structure Studied with Atomic Force Microscopy

Giovanni Dietler, Aleksandre Japaridze, Aleksandr Benke, Sylvain Renevey

Fluorescent dyes are widely used for staining and visualization of DNA in optical microscopy based methods. Even though for some dyes the mechanism of binding is known, how this binding affects DNA remains poorly understood. Here we present a novel experim ...

Contrast Enhancement in Optical Coherence Microscopy

Christophe Pache

Optical Coherence Microscopy (OCM) is a three-dimensional imaging technique that provides cross-sectional views of the subsurface microstructure of biological tissue, with a high axial and lateral resolution. In OCM, a low time coherence light source is sp ...
