Austrian BioImaging is proud to celebrate the launch of a new book on imaging technologies in tissue engineering and regenerative medicine, edited by Heinz Redl from the Institute of Traumatology at the Ludwig Boltzmann Society. This international volume brings together leading experts to create a unique, updateable resource for researchers......
This work introduces advanced microDECT imaging protocols that provide unprecedented visualization and analysis of microvasculature in intact tissue, enhancing our understanding of vascular structures in relation to soft and hard tissue morphology. By enabling the effective separation of vasculature from skeletal tissues and facilitating the integration of multiple staining techniques,......
Austrian BioImaging/CMI is proud to highlight new research by our member, Kareem Elsayad, from the Medical University of Vienna, which was recently published in the prestigious journal PNAS. In this work, Kareem and his team demonstrate that measuring blood plasma viscosity using Brillouin light scattering (BLS) spectroscopy is a valuable method......

Few research groups can single-handedly support the necessary equipment, expertise and personnel needed for the ever-expanding portfolio of technologies that are......
Kareem Elsayad and his research team at the Center for Anatomy and Cell Biology, a part of the Medical Imaging Cluster at MedUni Vienna, have made significant strides in addressing complex questions related to cellular mechanics. Their innovative technique utilizes Brillouin Light Scattering to image intricate mechanical features within the......
Determination of the oligomerization state of plasma membrane proteins and lipids is key to understanding cellular signaling and function. TOCCSL (thinning out clusters while conserving stoichiometry of labeling)—an imaging modality based on single-molecule fluorescence microscopy—allows for measuring the degree of homo- or hetero-oligomerization of membrane constituents even at expression levels......
A customized micropatterning approach combined with total internal reflection fluorescence microscopy was used to quantify ligand-induced FGFR3 receptor activation at the live cell membrane. Activation was recorded via the recruitment of the downstream signal transducer growth factor receptor-bound 2 (GRB2) to FGFR3 micropatterns. Authors: Ingrid Hartl 1, Veronika Brumovska 2, Yasmin Striedner 1, Atena Yasari 1, Gerhard J......
Magdalena C Schneider and Gerhard J Schütz describe how significance testing provides an important and valid addendum to the toolbox of quantitative (single molecule) biology. For two selected applications of single molecule microscopy – Nanoclustering in single molecule localization microscopy (SMLM) and single molecule tracking – they introduce how a single overall p-value......
Compared to room temperature experiments, SMLM performed under cryogenic temperature achieves higher photon yields and, hence, higher localization precision. However, to fully exploit the resolution it is crucial to account for the anisotropic emission characteristics of fluorescence dipole emitters with fixed orientation. We show here that astigmatic imaging in combination......
