Multi-organ chip detects dangerous nanoparticles

Innovative test system for toxic effects: Simulations help to optimize development

05-Oct-2022

What happens when we breathe in nanoparticles emitted by a laser printer, for example? Could these nanoparticles damage the respiratory tract or perhaps even other organs? To answer these questions, Fraunhofer researchers are developing the “NanoCube” exposure device. The Nanocube’s integrated ...

Print tumors in the laboratory

New 3D tumor model makes it possible to test cancer drugs in realistic tissue environment

20-Apr-2022

Using a bioink made from alginate and human cells, researchers at the Technical University (TU) Berlin and other institutions have printed a three-dimensional model of a cancer metastasis in healthy tissue. They used a commercially available bio-printer for this purpose, so that the tumor model ...

Biosensors made of cellulose

Recyclable, skin-friendly and biodegradable

21-Apr-2021

Electroencephalography (EEG), electrocardiography (ECG), electromyography (EMG) – all of these non-invasive medical diagnostic methods rely on an electrode to measure and record electrical signals or voltage fluctuations of muscle or nerve cells underneath the skin. Depending on the type of ...

AI-based analysis system for the diagnosis of breast cancer

For the first time, morphological, molecular and histological data are integrated in a single analysis

12-Mar-2021

Researchers at TU Berlin and Charité – Universitätsmedizin Berlin as well as the University of Oslo have developed a new tissue-section analysis system for diagnosing breast cancer based on artificial intelligence (AI). Two further developments make this system unique: For the first time, ...

Metabolism: Researchers first to shed light on structure of huge enzyme complex

A new method has enabled the natural structure of particularly large and complex enzymes to be revealed

11-Feb-2021

Scientists at Martin Luther University Halle-Wittenberg (MLU) and TU Berlin have published their findings in the journal "Cell Reports". They investigated a multi-enzyme complex that plays an essential role in metabolism and have discovered that it functions differently than previously thought. ...

X-ray pulses uncover free nanoparticles for the first time in 3-D

'Super microscope' reveals unexpected variety of shapes

10-Feb-2015

For the first time, a German-American research team has determined the three-dimensional shape of free-flying silver nanoparticles, using DESY's X-ray laser FLASH. The tiny particles, hundreds of times smaller than the width of a human hair, were found to exhibit an unexpected variety of shapes, ...

New holographic process uses image-stabilised X-ray camera

09-Jan-2014

A team headed by Stefan Eisebitt has developed a new X-ray holography method that will enable snap-shots of dynamic processes at highest spatial resolution. The efficiency of the new method is based on a X-ray focussing optics being firmly fixed to the object to be imaged. While this approach ...

Guinness World Record: X-ray laser FLASH shoots fastest movie

01-Feb-2012

It's official: The world's fastest movie was shot by DESY's X-ray laser FLASH in Hamburg. In its 2012 edition, the famous Guinness Book of World Records lists an interval of a mere 50 femtoseconds between two frames for FLASH. A femtosecond is a quadrillionth of a second, meaning that the two ...
