31.01.2020First introduced in the 1980s, stereolithography (SL) is an additive manufacturing process that prints 3D objects by the selective curing of liquid polymer resin using an ultra-violet (UV) light source in a layer-by-layer fashion. The polymer employed undergoes a photochemical reaction which turns it from liquid to solid when exposed to UV illumination.
13.01.2020Biological Engineers at the University of Bath have developed a test that could help medics quickly diagnose urinary tract infections (UTIs), using a normal smartphone camera.
10.01.2020Cells called corneal keratocytes are innately programmed to come to the rescue if the eye is injured. This natural healing process sometimes fails, however, resulting in scarring and blindness. Scientists are still trying to understand why.
01.02.2019Organ-on-a-chip systems are technically a great enhancement of medical research because they facilitate testing of active ingredients on cell cultures in the chambers of a plastic chip. This replaces animal testing and improves patient safety. That being said, they are not a true-to-life replication of the human body and can only simulate a few functions and activities.
01.02.2019In vitro processes and animal tests are used to develop new medications and novel therapeutic approaches. However, animal testing raises important ethical concerns. Organ-on-a-chip models promise to be a feasible alternative. In a system the size of a smartphone, organs are connected using artificial circulation.
24.07.2017A new analysis method that uses fetal DNA extracted from the mother’s blood is designed to non-invasively reach a prenatal diagnosis of genetic disorders in a child. A task force of the Hahn Schickard Society for Applied Research is an active part of the "ANGELab" project and co-developed this diagnostic procedure.
29.03.2017Retinitis pigmentosa is a hereditary eye disorder, which can lead to night blindness, restriction of the peripheral visual field and ultimately to blindness. The University Hospital Aachen, Germany, implants the Argus II retinal prosthesis system made by the Second Sight Company. It allows people with retinitis pigmentosa to perceive light and improve orientation.
