Machine learning assisted structure analysis reveals SARS-CoV-2 virus tactics
15/09/2021
The proteins of SARS-CoV-2 play key roles in how the virus manages to evade immune defense and replicate itself in patients’ cells. An international research team has now compiled the most detailed view of the virus' protein structures available to date. The analysis employing artificial intelligence methods has revealed surprising findings.
Technology takes the art of origami into the fight against COVID-19
13/09/2021
3D-printed origami technology at the heart of low-cost, portable ventilators aimed at improving pandemic treatment and revolutionizing healthcare delivery.
Engineers grow 3D bioprinted blood vessel
18/08/2021
A team in the Department of Biomedical Engineering, co-led by associate professor Dr. Akhilesh Gaharwar and assistant professor Dr. Abhishek Jain, has designed a 3D-bioprinted model of a blood vessel that mimics its state of health and disease, thus paving the way for possible cardiovascular drug advancements with better precision.
Programmable structures from the printer
08/07/2021
Researchers at the University of Freiburg and the University of Stuttgart have developed a new process for producing movable, self-adjusting materials systems with standard 3D-printers. These systems can undergo complex shape changes, contracting and expanding under the influence of moisture in a pre-programmed manner.
Orthopedic technology: 3D scanners change the industry
01/07/2021
Orthopedic technology involves taking a measurement of a specific body part and then creating a medical device, be it prosthesis or orthosis, that fits. While optical scanners are already used for some of these measurements, others are still performed through manual labor and craft to create molds of the body. 3D scanners are changing this.
Digital orthopedic technology: scan, customize, print
01/07/2021
When auxiliary means like orthoses or prostheses do not come from the shelf, but are adapted to the wearer, this means true crafting: In the past, a plaster mold of a body part had to be made as a template to create an individual aid from it step by step. Fortunately, we have come a long way until today.
Customized and freshly printed: 3D printing in orthopedics
01/07/2021
Creating custom-made medical devices to target individual patient needs: that is the core function and primary objective of orthopedics. Using 3D printers for this will make sense in the future. Luxinergy is an innovative Austrian technology company that specializes in the development of biocompatible resins and large-format 3D printers.
Getting from 3D scan to 3D print: computer-aided prostheses and orthoses
01/07/2021
Orthopedic technology is a true craft: That's because prostheses and orthoses are rarely off-the-shelf products. Orthopedic technicians must typically use different materials to custom create and fit the devices. Many of these processes are manual. For several years now, 3D scanning and 3D printing have modernized the industry thanks to digital design freedom and flexible production.
Multi-photon lithography: printing cells with micrometer accuracy
01/12/2020
How do cells react to certain drugs? And how exactly is new tissue created? This can be analyzed by using bioprinting to embed cells in fine frameworks. However, current methods are often imprecise or too slow to process cells before they are damaged. At the TU Vienna, a high-resolution bioprinting process has now been developed using a new bio-ink.
Bioprinting: life from the printer
01/12/2020
It aims at the production of test systems for drug research and gives patients on the waiting lists for donor organs hope: bioprinting. Thereby biologically functional tissues are printed. But how does that actually work? What are the different bioprinting methods? And can entire organs be printed with it? These and other questions are examined in our Topic of the Month.
Printed life – possibilities and limits of bioprinting
01/12/2020
Implants, prostheses and various other components made of plastic, metal or ceramics are already being produced by additive manufacturing. But skin, blood vessels or entire organs from the printer – is that possible? For years now, intensive research has been underway into the production of biologically functional tissue using printing processes. Some things are already possible with bioprinting.
"Cells are highly sensitive" – material development for bioprinting
01/12/2020
The big hope of bioprinting is to someday be able to print whole human organs. So far, the process has been limited to testing platforms such as organs-on-a-chip. That's because the actual printing process already poses challenges. Scientists need suitable printing materials that ensure the cell's survival as it undergoes the procedure. The Fraunhofer IGB is researching and analyzing this aspect.
rhCollagen: genetically engineered building block for regenerative medicine
03/02/2020
Collagen is the stuff that holds our bodies together and that houses our cells. In regenerative medicine, it is also the stuff that can be applied to wounds to support healing. However, collagen from animal or human sources has some drawbacks for today’s medicine. This is where rhCollagen from the Israeli company CollPlant comes into play.
Regenerative medicine: helps the body healing
03/02/2020
Severe wounds heal slowly and leave scars. This is why we have been using regenerative therapies for some time now to accelerate and improve healing. They also help to avoid permanent damage. Still, complex applications like replacing organs or limbs will rather remain vision than become reality for a long time.
Regenerative medicine: creating a new body?
03/02/2020
Regenerative medicine aims to repair the human body after injuries, accidents or major cancer surgery. Unfortunately, we are still not at a stage where this process can achieve optimal results for every conceivable situation. Having said that, various new methods are on the cusp of breakthrough.
Endoprosthetic surgery: modern and traditional approaches
01/01/2020
Surgery is required if you need an artificial joint. Patients and doctors must select the type of surgery that’s best suited and choose between robot-assisted, traditional or minimally invasive surgical approaches. Post-operative risks should be kept to a minimum, while benefits should outweigh any possible complications.
Tissue engineering: how to grow a bypass
23/04/2018
A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.
