Wound monitoring using sensory nanofibres

Monitoring the condition of chronic, non-healing wounds requires wound dressings to be changed at short, regular intervals. In the EU-funded WOUNDSENS project, researchers at the NMI in Reutlingen are using electrospinning to produce novel types of wound dressings. These consist of biosensory fibres that send information about the condition of the wound to the outside, thereby improving inflammation detection.

Medicine of the future: intelligent 4D polymers from the printer

It is impossible to imagine medicine without 3D printing, which can be used to make implants or for culturing cells and tissues. It is now possible for 3D objects to be given an added dimension, namely an ability to make simple autonomous movements, by changing their size. Researchers at Heidelberg University have been able to produce microscopically small 4D structures from intelligent polymers that can be tailored to individual requirements.

Researchers of the University of Freiburg introduce biosensor for the nucleic acid amplification-free detection of SARS-CoV-2 RNA.

From human intestines to the bottom of the sea: Microorganisms populate nearly any habitat, no matter how hostile it is. Their great variety of survival strategies is of huge potential in biotechnology. Most of these organisms, however, are unknown, because they cannot be cultivated.

Biosensor for whole blood and exhaled breath analysis - 02/02/2022

Antibiotic detection from whole blood or exhaled breath possible

Incorrectly dosed antibiotics are not only dangerous for patients, but also often the cause of resistant strains of bacteria. Researchers at the University of Freiburg have developed a biosensor to determine the effective amount and thus enable personalised therapy. The biosensor works by rapidly determining small amounts of the substances directly from whole blood or exhaled breath.

The cochlear implant (CI) is the most successful neural prosthesis worldwide. Thanks to direct stimulation of the auditory nerve, it enables more than half a million people worldwide to hear, even though those affected were born deaf or deafened.

A team of engineers and biotechnologists at the University of Freiburg has for the first time shown in mammals that the concentration of antibiotics in the body can be determined using breath samples. The breath measurements also corresponded to the antibiotic concentrations in the blood. The team’s biosensor – a multiplex chip – will in future enable personalized dosing of medicines against infectious diseases on-site.

Epigenetic switches in bacteria as biosensors

The analysis of pathogen biomarkers and biomarkers for the diagnosis of diseases can be crucial for health. However, the detection of pathogens and diseases depends on a sensitive and reliable method that delivers rapid results. Biosensors have such properties. Researchers at the Institute of Biochemistry and Technical Biochemistry (IBTB) at Stuttgart University have constructed an epigenetic circuit composed of plasmids that might make it…

Miniature organs with great potential

Dr. Peter Loskill and his team at the Fraunhofer Institute in Stuttgart and the University Hospital of Tübingen are developing what is known as an "organ-on-a-chip" (OoC). An OoC is a microfluidic system that simulates small functional units of organ tissue. OoCs can be used in different ways: in basic and pharmaceutical research as well as in clinical research and application, where they might render many animal experiments…

TGU Varimol - 24/07/2020

Click chemistry for new medical procedures

Using a simple molecular click process, biochemists have been able to connect ring-shaped molecules with each other and couple therapeutically active substances to these molecules. Drugs can thus be specifically delivered to diseased cells and used for imaging processes or biosensors. The Stuttgart-based start-up Varimol is using this new technology to provide its customers with tailored applications that are as simple to use as a kit.

Diagnostics with molecular scissors – is this also possible for on-site COVID-19 tests?

The CRISPR-Cas gene-editing technology is one of the most important developments in molecular biology in recent years. It utilises molecular scissors with which nucleic acids can be cut and edited almost arbitrarily. Researchers in Freiburg, Germany have now successfully used the technology for diagnostic purposes. They are currently working intensively on expanding the system to enable it to detect genome sequences of the novel SARS-CoV-2 virus.
