Biological imaging ranges from the visualization of ions, molecules, cells and tissues to whole small animal models, and is one of the most used and demanded technologies in life science related research, teaching and industrial applications. The BF-BioImaging platform supports, maintains, and develops a powerful portfolio of various state-of-the-art equipment and expertise in a wide range of light and electron microscopy services, including light microscopy modalities for both fixed samples and live cell and tissue imaging, ranging from super-resolution to light sheet and mesoscopic imaging, and from label-free imaging to high-content microscopy. Electron microscopy offerings cover standard and cryo-genic specimen preparation for transmission and scanning electron microscopy, three-dimensional imaging at wide length scales and various hybrid techniques with light microscopy.
The platform comprises over 50 full-time RI personnel in 12 imaging units organized into 5 nodes in Helsinki, Turku, Oulu, Tampere, and Kuopio. The platform serves a large user base of >1400 users, has contributed to several patents, start-ups, and company collaborations, and supports other BF technology platforms by providing various microscopy-based readouts and analysis tools.
BF-BioImaging platform services include:
- Open access to all facilities
- Personal user support and general support activities: e.g., consultation on experimental set up; sample preparation; choice of instruments and imaging methods; image analysis; user training & guidance
- Maintenance and development of imaging systems, methods and analytics
