Studying optical nanoantennas: customer story from Chalmers University of Technology

Posted by Delmic on Jun 18, 2018 12:15:00 PM

One of the applications of cathodoluminescence is studying optical nanoantennas. But what are they exactly? These devices, made usually from noble metals (gold or silver, for example) or from semiconductor materials, are capable of amplifying and manipulating light on the nanoscale.
Dr. Ruggero Verre is one the Delmic’s oldest customers: he is a post-doctoral researcher in the Department of Applied Physics at the Chalmers University of Technology in Gothenburg, Sweden. Optical nanoantennas is the focus of his research group, headed by Prof. Mikael Käll.

One way to study the properties of the antennas and understand how they work is by characterizing them with cathodoluminescence. The group of Ruggero Verre has been using the SPARC cathodoluminescence detector to study them, and they have achieved some interesting results.

Fluorescent world of marine microorganism: customer story

Posted by Delmic on May 28, 2018 1:20:00 PM

Studying microorganisms (or microbes), which are found in the ocean waters, is a fascinating process that can reveal the hidden secrets about ocean chemistry, biology and climate. Marine microorganisms are exceedingly small, diverse in their forms and distributed across the ocean, which makes it so challenging to analyze them.

Still, marine microbiologists are searching for the answers that will help us to understand the ocean’s ecosystem and how it influences us. This is the focus of the research group of Dr. Sten Littman from Max Planck Institute for Marine Microbiology.

Integrated correlative light and electron microscopy: A new technique for geological materials

Posted by Delmic on May 3, 2018 3:00:00 PM

Integrated correlative light and electron microscopy (iCLEM) is a technique, in which both fluorescence imaging and electron imaging can be performed on one instrument without needing to transfer the sample. Correlative microscopy approach is being used worldwide for cancer research, in marine biology, neuroscience, and cell biology. Recently this technique has also been applied in the field of geology to gain an insight into the sedimentary organic matter in geological materials.

How Does Correlative Microscopy Work?

Posted by Delmic on Apr 13, 2018 1:30:00 PM

Nowadays it has become crucial for life scientists to gain structural and functional data about the sample in order to understand the biological processes happening at the scale of the nanometer. Light or fluorescence microscopy made it possible for the researchers to detect the functional information and image different colors and parts of the cell. It provides the data to understand the dynamics of the cell, however, the diffraction limit of light doesn’t allow distinguishing objects that are smaller than the wavelength of light. That is when the life scientists turn to electron microscopy, which provides the structural information in a high resolution.

An inside look at the department of Imaging Physics, TU Delft: The breeding ground for innovations in iCLEM

Posted by Delmic on Sep 28, 2017 4:29:42 PM

Understanding the relationship between structure and function in biology requires continuous developments in the field of microscopy. While electron microscopes and fluorescence microscopes have been go-to techniques for studying organic samples at a high resolution, individually they fall short in offering the exhaustive data needed for truly in-depth life science research.

In 2011, the Charged Particle Optics group at TU Delft completed the development of the SECOM. This system integrates a light and electron microscope, thus combining the labelling capabilities of fluorescence microscopy with the high-resolution nanoscale data obtained from electron microscopy. Six years later, the department of Imaging Physics houses no less than five SECOM systems.
