Nano and Molecular Systems 

Nano and Molecular Systems (NANOMO) has a long record in developing and utilising synchrotron radiation (SR) sources and instrumentation at various international SR facilities. The core research of NANOMO is on the electronic structure and dynamics of nanoparticles (metal clusters, environmental aerosols), heavy metal substances, applied spectroscopy, and novel functional materials development. Extensive international collaboration has provided a solid base for the research directions. This is verified by the 42 publications in international leading journals in 2011-2015, including Nat. Commun. Sci. Rep., Phys. Rev. Lett., PCCP and Surf. Rev. Lett. NANOMO has carried out pioneering research especially in the rapidly developing field of photon sciences. The group is a core part of the Molecular Materials Research Community. Use of the unique properties of SR has allowed the group to establish exceptionally wide interdisciplinary collaborations with technical, bio and medical sciences, as well as mining research at University of Oulu.

Centre of Excellence in Cell-Extracellular Matrix Research

The Centre of Excellence in Cell-Extracellular Matrix Research (CoE Cell-ECM) is one of the world´s leading centres in the field of extracellular matrix research (ECM) and it is an integrated consortium of six research groups at the University of Oulu. The CoE
Cell-ECM has a strong internationally recognized research profile, and its principal investigators are leading scientists in the fields of ECM biology, cardiovascular research, hypoxia responses, developmental biology, and cancer genetics. The CoE Cell-ECM groups are affiliated to Biocenter (BCO), the spearhead of research in biosciences and molecular medicine at the University of Oulu. Together with imaging centers at bioinstitutes in Helsinki and Turku, BCO forms the Finnish Euro-BioImaging Node for the pan-European imaging infrastructure network. Expertise at the CoE Cell-ECM covers a very wide spectrum of model organisms, in vitro cell and organ culture techniques, and biochemical approaches. To utilise advanced model systems, many of these developed by the CoE ECM scientists, molecular and cellular imaging methods are the key research techniques. Special expertise exists in mouse tissue imaging (tissue sections and whole mount preparations), long-term time-lapse imaging of cells and organoids in 3D matrices using confocal laser scanning microscopy techniques, ECM molecular imaging (confocal laser reflection, total internal reflection microscopy techniques, transmission and electron microscopy, multiphoton), and 3D imaging methods for microscopically large specimens (optical projection tomography and light sheet techniques, that were pioneered in Finland by the CoE Cell-ECM researchers. Use of advanced imaging methodologies has allowed publication in high impact journals including Nat Genet , Nat Cell Biol, Circ Res, PNAS, J Am Soc Nephrol, J Clin Invest, J Natl Cancer Ins., and Development.

Structural Enzymology

Structural Enzymology (SE) research group has internationally respected expertise in structural biology and biocatalysis by enzymes and complexes involved in lipid metabolism from human and pathogenic organisms such as Mycobacterium tuberculosis and Trypanasomatidae. The group has published articles in high-ranking journals, e.g. ACS Chem. Biol. and Nat. Commun. The SE group has well established complementary research collaborations within and outside the EU, including on chemistry and directed evolution. The applications of the SE group research include fundamental understanding of the mechanisms of enzymes, developing enzymes with novel activities, and drug discovery. SE research benefits from the excellent in-house protein crystallography core facility (a National Affiliated Centre of INSTRUCT) and European SR sources such as ESRF, Diamond, and MAX IV. Our faculty is one of the EU-BIOSTRUCT-X and iNEXT training TID centres. The group is very actively involved in the development of xtalPiMS, a crystal visualisation and crystal data tracking software, together with the Diamond Light Source at UK. The SE group has actively participated in organising high level workshops focusing on protein crystallography, EMBO courses and, in future, also the EMBO conference on biocatalysis.

Fibre and Particle Engineering

Fibre and Particle Engineering (FPE) focuses on modifications of cellulosic fibres and materials and composites made from cellulose fibres and cellulose nanomaterials (nanocrystals, CNCs and –fibres, CNFs). The fabrication techniques of functionalised CNCs and CNFs and their use in bionanomaterials are the international spearheads of the FPE research. The CNCs and CNFs can be used to introduce e.g. high mechanical strength, biodegradability, lower weight and higher specific surface area to materials, which make them appealing for a wide variety of uses ranging from sustainable packaging to medical materials and water chemicals. The research is at a high international level and has recently received an additional boost with the appointment of Finland Distinguished Professor (FiDiPro) Kristiina Oksman.

Genetics and Physiology

The research of Genetics and Physiology (GP) group focuses on biosciences and especially on genetics, plant, and animal physiology. The GP research group includes two supervisors (Häggman, Pirttilä), and currently 4 post-docs, 7 Ph.D. students, and >10 PhDs have graduated from the group in the past. The group has funding record including Academy of Finland, TEKES and EU, and belongs to Northern Bioeconomy research community (NORBE, http://www.oulu.fi/bioeconomy/node/16286), which was ranked high within the university of Oulu in RAE2013.  The group has publications in high-impact journals, e.g. Nature Biotechnology and Nature Chemical Biology. We have a large network of research collaborations within and outside the EU, such as ETH Zurich, Austrian Institute of Technology, Umeå Plant Science Center, and NC State University (USA). The research includes a wide range of studies from microbial community analyses to cell biology and from biotechnological approaches to applications in sequencing technology, however, various imaging methods are at the core of our research projects. For instance, gene expression studies provide important data, but through in situ hybridization or GFP labeling, coupled with light, fluorescence, or confocal laser scanning microscopy, gene expression can be localized into a specific cell or tissue. On the other hand, we can study if the proteins of interest are interacting e.g. by BiFC assay. Several staining assays, e.g. TUNEL assay, are important to understand the processes going on in the tissue under study.  Furthermore, through analysis of protein crystal structures, or by structural modeling, support can be obtained for the supposed functioning of a protein.
