07.11.2019Where bones fracture, surgeons often have to join the fragments with implants. Magnesium orthopaedic screws, which over time dissolve in the body, spare patients another operation after healing is completed and reduce the risk of infection. To develop optimized alloys and orthopaedic screws with functionalized surfaces, Empa researchers are now investigating magnesium corrosion.
04.11.2019Scientists of Tomsk Polytechnic University jointly with the University of Montana (USA) proposed a new promising material for regenerative medicine for recovery of damaged tissues and blood vessels.
31.10.2019Imagine a runner who doesn't need to carry a stopwatch or cell phone to check her time: She could just gaze at the glowing stopwatch display on the back of her hand. Such human-machine interfaces are no longer science fiction, but they still have a way to go before becoming mainstream.
30.10.2019Drugs can be safely delivered to cancerous lymph nodes via the lymphatic system and then released inside the nodes using sound waves. Tohoku University researchers tested the treatment on mice with metastatic breast cancer and published their findings in the journal Scientific Reports.
24.10.2019A biomimetic blood vessel was fabricated using a modified 3D cell printing technique and bioinks, which were formulated from smooth muscle cells from a human aorta and endothelial cells from an umbilical vein.
09.10.2019Physiological parameters in our blood can be determined without painful punctures. Empa researchers are currently working with a Canadian team to develop flexible, biocompatible nanocellulose sensors that can be attached to the skin. The 3D-printed analytic chips made of renewable raw materials will even be biodegradable in future.
02.10.2019Small, non-invasive patches worn on the skin can accurately detect the levels of medication in a patient's system, matching the accuracy of current clinical methods. In a small-scale clinical evaluation, researchers at Imperial College London have shown for the first time how microneedle biosensors can be used to monitor the changing concentration of antibiotics.
25.09.2019Nanolaser has potential to treat neurological disorders or sense disease biomarkers. Researchers have developed a tiny nanolaser that can function inside of living tissues without harming them. Just 50 to 150 nanometers thick, the laser is about 1/1,000th the thickness of a single human hair.
25.09.2019The Fraunhofer FEP has developed a process, called SULEEI, which makes it possible to sterilize and preserve decellularized pericardial tissue by means of photo-initiated ultraviolet crosslinking with low-energy electron irradiation.
23.09.2019Researchers at the University of Helsinki in collaboration with researchers from Åbo Akademi University,Finland and Huazhong University of Science and Technology,China have developed a new anti-cancer nanomedicine for targeted cancer chemotherapy. This new nano-tool provides a new approach to use cell-based nanomedicines for effcient cancer chemotherapy.
20.09.2019Patients with the rare Loeys-Dietz syndrome suffer from aortic enlargement which may result in sudden over-expansion and a fatal aortic tear. In order to prevent this from happening, an aortic prosthesis must be implanted.
19.09.2019Not all bacteria spread diseases, many are beneficial and this strain has nanoscale syringes that deliver proteins which cause metamorphosis in marine animals, and could be modified as a novel drug delivery tool for future vaccines and cancer care.
18.09.2019A new needle-free flu vaccine patch revved up the immune system much like a traditional flu shot without any negative side effects, according to a study. Though the research is in the early stages, it's an important step toward a technology that could replace needle-based vaccination methods that require administration by health care workers and biohazard waste removal.
12.09.2019Liquid-like tissue behavior is a key principle for the formation of structures in biological systems. Researchers at the Max Planck Institute of Colloids and Interfaces in Potsdam have shown that growing bone tissue behaves like a viscous liquid on long time scales, thereby accepting forms with minimal surface area.
11.09.2019Researchers at KU Leuven in Belgium have developed a technique to make sheep produce new antibodies simply by injecting the DNA building blocks. This approach is much cheaper and more efficient than producing antibodies industrially and administering them afterwards. The study in animals with a similar size as humans brings us a step closer to the clinical use of antibody gene therapy.
08.11.2018Not enough exercise, an unhealthy diet: Kidney stones develop when urine contains too many insoluble compounds and are now one of the most common diseases worldwide. The ailment annually affects 1.2 million people in Germany alone. The stones are broken up and taken out via endoscopic surgery. Now it’s possible to remove even the tiniest residual fragments. The solution: a biocompatible adhesive.
