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.
01.02.2019The liver, nervous tissue or the intestines: all are important human organs that have in the past been tested for their function and compatibility using animal or in vitro test methods. In recent years, TissUse GmbH, a spin-off of the Technical University of Berlin (TU Berlin), has launched multi-organ chip platforms. But that’s not all.
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.
21.11.2018Our blood reveals a lot about our physical health. The shape of our blood cells sheds light on several hereditary diseases for example. For a diagnosis, the cells must first be examined under the microscope and categorized into a specific cell class. We met with Dr. Stephan Quint and Alexander Kihm of the Institute of Physics at the Saarland University, who explained how this classification works.
09.07.2018People who are not ill and do not show any symptoms typically do not visit the doctor. And while most people know that preventive medical checkups for cancer, for example, are important, they still avoid them. They tend to be very hesitant because the doctor might detect a serious illness. In the future, a new type of implant could make it easier to go to a screening test.
22.06.2018A drop of blood provides a lot of valuable information. However, it takes several hours to analyze the blood of a patient and make a diagnosis. This takes away a lot of time that's crucial for treatment. A new method intends to considerably speed up this process by testing the cells in the blood in terms of their deformability and immune response.
23.04.2018A 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.
01.03.2018Everyone is different. This statement also applies to our health. Cancer, in particular, can look and progress differently depending on the individual person. That’s why every patient ideally also needs a customized treatment that is tailored to their individual needs. But how feasible is this idea?
22.02.2018Here on Earth, all experiments are bound by gravitation. Yet, freed from gravity's grip, tumor cells, for example, behave in an entirely different way. As part of the "Thyroid Cancer Cells in Space" project by the University of Magdeburg, smartphone-sized containers carrying poorly differentiated thyroid cancer cells are sent into space.
08.01.2018Few patients with heart failure are fortunate enough to receive a donor's heart. Ventricular assist devices (or heart pumps) have been around for several years and are designed to buy time as patients wait for a transplant. Unfortunately, the body doesn't always tolerate these devices.
22.08.2017Physics has always supported medical science, especially when it comes to practical implementation. Now physicists and health professionals join in collaborative research at an interdisciplinary Center in Erlangen and incorporate fundamental principles of theoretical physics in their studies of diseases.
01.08.2017Many therapeutic drugs are very powerful, but they are also very toxic at the same time. Thus, they have to be measured regularly, again and again, so that an adjustment of the individual drug dosage can be made. Until now, the "normal" way was to take the blood sample, send it to a central laboratory and get the results after some days. A new point-of-care test can measure it in 15 minutes.
14.07.2017A microscope that is only a few millimeters in size and that can help to consider cell changes in real time. This is the goal of the EU project ChipScope. Scientists led by Dr. Hutomo Wasisto in Braunschweig help to make this project come true.
03.07.2017Precision work is absolutely essential in eye surgery since the surgical site is very minute and sensitive. This is why eye surgeons have been using lasers for years. Femtosecond lasers are especially well suited to serve this purpose because they are able to cut tissue with great precision and little energy, which prevents unwanted side effects of surgery.
