Smart technology for better health
The rapid development of micro and nanotechnology has meant many applications that make it easier for us; who does not have a "smart-phone" today, which we can hardly be without? But the technology can also be used in other areas such as health. At the department, research is conducted on several health-related projects where the technology is used to improve or create entirely new applications.
Durable joint implants
A risk with hip arthroplasty is that the abrasive particles generated in the joint are collected between the body's bone tissue and the implant itself. These particles can cause inflammation, which over time leads to the bone tissue to be restored and the implant loosens. We develop a durable surface layer of ceramic thin film that limits the problem in several ways. First, the wear itself decreases. Second, the body can break down the few abrasive particles that are formed after all, so that they do not have time to cause inflammation. Third, the thin film prevents metal ions from the implant's main structure from leaking into the body.
Cellulose virus filter
Nanocellulose has about 100 times more surface area per unit weight than ordinary paper. It opens opportunities to develop new materials for medicine and health. Among other things, the cellulose is used for virus filtration by tailoring the distribution of the pore size of a paper filter. Virus particles are about a thousand as thin as a strand of hair which makes them very difficult to remove by filtration. One ambition is to develop a paper filter that filters out viruses "as easily as brewing coffee". The filter is adapted for both medical use and water purification where viruses are a major problem.
Measure the healing process with microwaves
Many children are born today with not fully developed skull. Surgeons can then repair the skull with an implant. Unfortunately, the healing process must be checked at regular intervals to avoid complications, which is quite expensive and complicated today. Researchers at the department have therefore developed a sensor that can continuously measure the healing process with the help of microwaves. The sensor is made of flexible material and is therefore easy to carry. The new sensor makes life much easier for both patient and physician.
