SiMBION NODE
The Slovenian national consortium SiMBION consists of 15 infrastructure centres and institutional departments. It is committed to provide part of its existing bioimaging capacities to external users, including access to imaging infrastructure, imaging methodology, sample preparation, advisory help in project planning, as well as training courses for Euro-BioImaging users. The consortium partners are traditionally providing part of their research infrastructure capacities to external national and international users within numerous national and international projects, individual collaboration and commercial contracts, including Transnational Access (TNA) programme of the EU.
Offered Technologies:
- Laser scanning confocal microscopy (LSCM/CLSM)
- Total internal reflection fluorescence microscopy (TIRF)
- Fluorescence Recovery after Photobleaching (FRAP)
- TEM of chemical fixed samples (TEM)
- TEM of cryo-immobilized samples (TEM cryo samples)*
- Immuno-gold EM on thawed cryo-sections (Tokuyasu-EM)
- Immuno-gold EM on resin sections (resin-EM)
- Scanning Electron Microscopy (SEM)
- micro-MRI (Field >= 7 T)(HF)
- micro-MRI (Field <7 T)(LF)
- ex-vivo micro-CT
Specialties and expertise of the Node
The consortium SiMBION was formed by merging the majority of the existing national research infrastructure resources in the field of bioimaging. The existing infrastructure, developed in the last decades within the hosting institutions by different institutional initiatives and funds, is distributed among several constitutive partners. In these circumstances, a multi-sited Node provides a framework that could at present efficiently merge this distributed research infrastructure and incorporate eventual dedicated Euro-Bioimaging infrastructure investments in the future. The existing collaborative workflows between the members of the SiMBION consortium, efficiently exploit the existing state-of-the art bioimaging techniques and the available supporting laboratories and bioimaging techniques available in a very small geographical area, providing excellent conditions for the execution of complex research projects and multimodal imaging procedures. This proposed structure and the workflows can only be provided in the form of multi-sited node.

Instrument highlights
Microanalytical centre of Jožef Stefan Institute is providing Transnational Access to ion-beam based state-of-the-art techniques for tissue chemical (elemental and molecular) imaging within EU H2020 project No. 824096 RADIATE (2019-2022). Up to 20% of total infrastructure capacity of 4000 beam hours unit of TNA access, beam hour) annually are allowed for TNA access within this EU project. From 300 to 600 beam hours (annually are provided to users of ion beams, of which 70 % are applied for chemical imaging of biological tissue. Proposal submission and evaluation are centralized (https://www.ionbeamcenters.eu/radiate/radiate-transnational-access/application-for-transnational-access/).
At the National Institute of Chemistry, a state-of-the-art LA-ICP-MS facility provides high-resolution elemental imaging of biomaterials for most elements of the periodic table, and localization, sizing, and counting of metal nanoparticles in tissues. Due to a linear dynamic range of up to 10 orders of magnitude, and detection limits of 10’s of parts per billion, the technique can address scientific problems in many disciplines. The technique has been applied in the field of metal-labeled antibodies designed to target specific antigens, metalloproteins, drug penetration in healthy and tumor tissues, elemental and nanoparticle uptake by plants, animals, and single cells.
