Electrodes grown in the brain – paving the way for future therapies for neurological disorders

02.03.2023

The boundaries between biology and technology are becoming blurred. Researchers at Linköping, Lund, and Gothenburg universities in Sweden have successfully grown electrodes in living tissue using the body’s molecules as triggers. The result, published in the journal Science, paves the way for the formation of fully integrated electronic circuits in living organisms.

Technology in wound care: tools for better healing

01.12.2022

Wounds – both acute and chronic ones – can have many different causes. They all have in common that they require meticulous care because complications in wound healing can severely reduce both the patients’ health and quality of life. But there is more to modern wound care than just cleaning and bandaging them. Nursing staff and physicians can also access technical aids for this work.

Wound care: healing with technology

01.12.2022

Wound care by nurses is directly about cleaning, sterile covering, and documentation. Medical and surgical interventions may also be necessary. In this context, wound care also offers potential for the use of technical aids that can help prevent complications.

Fibers for fibers – Textile implants repair the body

08.06.2022

We are nowadays already able to weave implants out of artificial fibers that can replace tissue or heal injuries. Different materials like polymers or nitinol are used to create flexible shapes. But the materials and their uses can still be improved.

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.

"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.

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.

Medical products made of collagen - Biocompatible, elastic, stable

19.03.2020

Regenerative medicine often relies on implants and materials that support healing in our body. Collagen has a special significance here. It is compatible to the body and offers an excellent environment for the growing of new cells. In our video, we took a look on where collagen and collagen products for medicine come from.

Cardiac Tissue Engineering: a heart out of the Petri dish

23.09.2019

For patients waiting for donor organs, every day can mean the difference between life and death. Making things even more complicated is the fact that not every organ is a compatible match with the patient. It would mean enormous progress if we could grow organs from the patient's own cells in the lab. That's why patients with heart disease place big hope in tissue engineering.

Multi-organ chips: Drug research without animal testing at vasQlab

15.05.2019

New active substances that are suitable for drugs are initially tested in animal experiments. However, the results cannot always be transferred to the human organism. At the Karlsruhe Institute of Technology, Prof. Ute Schepers from vasQlab explains how active substances can be tested in human tissue without endangering human health.
