4Pi-RESOLFT Nanoscopy
Here we apply the 4Pi scheme to RESOLFT nanoscopy using two-photon absorption for the on-switching of fluorescent proteins. We show that in this combination, the lobes are so low that low-light level,…Read articleFrom Light to Mind: Sensors and Measuring Techniques in Confocal Microscopy
This article outlines the most important sensors used in confocal microscopy. By confocal microscopy, we mean "True Confocal Scanning", i.e. the technique that illuminates and measures one single…Read articleCorrelating Intravital Multi-Photon Microscopy to 3D Electron Microscopy of Invading Tumor Cells Using Anatomical Reference Points
Cancer research unsing multiphoton microscopy and 3D electron microscopy. Correlative microscopy combines the advantages of both light and electron microscopy to enable imaging of rare and transient…Read articleThird Harmonic Generation Microscopy – Label-Free 3D-Tissue Imaging and Blood Flow Characterization
THG microscopy as special variants of multiphoton microscopy. Third Harmonic Generation (THG) microscopy is a non-fluorescent multi-photon technique that combines the advantages of label-free…Read articleInterview with Dr. Gertrude Bunt and Prof. Fred S. Wouters on the FOM 2015
Only a few days to go before the start of Focus on Microscopy 2015 in Göttingen, Germany. This year’s FOM is being organized by Dr. Gertrude Bunt and Prof. Dr. Fred S. Wouters from the University…Read articleDeeper Insights in Transparent Animals
CLARITY clearing derivatives for multiphoton microscopy. Transparent organisms help us to identify spatial arrangements and connections of cells and tissues, especially neuronal circuits can easily…Read articleSingle-Cell Phenotyping within Transparent Intact Tissue through Whole-Body Clearing
Understanding the structure-function relationships at cellular, circuit, and organ-wide scale requires 3D anatomical and phenotypical maps, currently unavailable for many organs across species. At the…Read articleThe Environment Makes the Stem Cell
A recent publication in Nature shows that all stem cells divide and compete for niche space by passively "kicking out" others so that eventually one stem cell takes over the whole niche. Jacco van…Read articleSmart Control for Resonant Galvo Scanners
High time-resolution confocal microscopy (HTRCLSM) requires fast scanning devices. Whereas non-resonant galvo scanners allow full position control, but only at slow speed, resonant scanners allow…Read articleTracking Glomerular Fate Over Long Time Distances
Multi-channel multiphoton microscopy with dedicated optics for CLARITY. The glomerular filtration barrier (GFB) is a complex spatial structure within the kidney glomerulis where ultrafiltration…Read articleDevelopments in Multiphoton Excitation Microscopy
Basics, history, and applications of multiphoton microscopy. Honouring Goeppert-Mayer’s prediction of simultaneous two-photon absorption by an atom or molecule reported in the 1930s in her PhD…Read articleOrder versus Disorder
In modern biomaterial design the generation of an environment mimicking some of the extracellular matrix features is envisaged to support molecular cross-talk between cells and scaffolds during tissue…Read articleGood Vibrations
In recent years, new molecular imaging techniques, such as coherent anti-Stokes Raman scattering microscopy (CARS), have been developed for rapid vibrational imaging of living cells.Read articleCARS and Confocal
The most important drawback of single-photon and multiphoton confocal microscopy is the need to label the specimen. CARS (Coherent Anti-Stokes Raman Spectroscopy) addresses this issue because it is…Read articleDeep Tissue Imaging
