Exploring How Life Interacts with Metal
The LIMES project investigates the dual nature of biological interactions on metal surfaces—essential in both health and industry. While the ability of human cells to integrate with metal implants is critical for medical success, unwanted bacterial adhesion can lead to difficult-to-treat infections. These same microbial processes also impact biotechnological industries, where biofilm formation on metal can reduce product yield and quality.
LIMES aims to understand the interface where cells, bacteria, and metals meet. The goal is to engineer materials and surface properties that promote tissue healing while resisting microbial colonisation—advancing both health care and industrial applications. LIMES builds directly on the findings of the MISFAITH project.
"We are proud of this achievement by the Department of Biomaterials," says Dean Hans Jacob Rønold. "As highlighted in the EVALMEDHELSE report from the Research Council of Norway, our faculty has significant potential for further excellence in research, education, and innovation through international collaboration. This grant reinforces one of our leading research environments."
A Global Collaboration Tackling a Global Challenge
The LIMES consortium brings together researchers from:
-
University of Oslo (Norway) – with leading groups in biomaterials, clinical dentistry, and microbiology (Department of Biomaterials, Faculty of Dentistry and Prof. Dirk Linke's group at the Department of Biosciences).
-
Edo State University (Nigeria) – with strengths in environmental and food biotechnology.
-
Nagoya University (Japan) – known for advanced materials science and engineering.
-
Dongguk University (South Korea) – specialising in biomedical innovation and translational research.
This highly interdisciplinary network combines expertise in microbiology, material science, engineering, chemistry, and clinical dentistry.
Education Through Research
A core component of LIMES is its dedication to training the next generation of researchers through hands-on, cross-border collaboration. Master's and PhD students will take part in lab exchanges, international workshops, summer schools, and joint courses.
The project also emphasises responsible innovation, offering students training in intellectual property rights, gender balance in research, and industry collaboration—preparing them not just as scientists, but as future leaders.
New Technologies and Tools
To meet its ambitious goals, LIMES will develop novel tools for studying microbial and cell behaviour on metal surfaces. These methods will accelerate the design of new materials while reducing the need for animal testing.
Looking Ahead
The LIMES project holds significant promise for generating broad societal impact across healthcare, biotechnology, and sustainability. In the healthcare sector, the goal is to contribute to the development of safer and more durable implants while reducing the reliance on antibiotics to combat infections. In the biotech and food industries, improved control over microbial activity may lead to more efficient and stable production processes. From a sustainability perspective, LIMES encourages better resource utilisation, minimises the need for antimicrobial agents, and reduces dependency on animal testing through advanced in vitro modelling.
LIMES will facilitate international research stays, provide open educational resources, and culminate in a major international conference. In doing so, it will not only generate new scientific knowledge but also foster a globally connected cohort of young researchers equipped to address future challenges in infection control, implantable biomaterials, and sustainable technology.
The LIMES project is supported by the Research Council of Norway (RCN) and the Norwegian Directorate for Higher Education and Skills through the INTPART programme (Grant number: 359679).
