Detect cell changes faster


Scientists are researching how changes in cell cultures of cartilage and soft tissue can be detected in a cooperative research project of the University of Applied Sciences Zwickau (WHZ), the Fraunhofer Application Center for Surface Technologies and Optical Metrology (AZOM) and the Research Institute of Leather and Plastic Sheets (FILK).

The research project focuses on cell monitoring and the early detection of cell changes or damages. This is particularly important when testing the tolerance of new drugs or cosmetics. In conventional tests, cell health is detected by means of biochemical tests, which determine, for example, the metabolic cell activities.

The effect can often only be seen after several days. Transitional states and information on when exactly the first alteration occurs are not yet recorded.

Thus, the efficacy can only be assessed by the final result. In the case, for example, that a drug causes a particular reaction in the cells at an early point in time, it is not possible to detect the reaction at the end of the experiment.

New optical measuring method developed

Here, the collaborative research project comes into play. For the investigation of cell vitality, especially in cartilage and soft tissue, the Leupold-Institute for Applied Natural Sciences of the WHZ together with Fraunhofer AZOM developed a new optical measuring method, which allows an online cell measurement.

The principle relies on a "white light laser", also known as a supercontinuum source. With intense, ultra-short pulses, it facilitates a non-destructive analysis of cell cultures. The experiments employ primary cells isolated from tissue. These are cultivated in the FILK biological laboratory and placed in different states, e.g. by toxin additions.

The scientists are developing an automated optical measurement procedure for evaluating and recording the material change as well as the size of cell components. Using new data analysis methods, the cell states are now recorded time resolved with high sensitivity. The technology facilitates the analysis of thick, deeper cell structures, an important aspect for investigations on three-dimensional cell cultures and tissues.


In research, cells are studied to identify disease mechanisms. Individual cells or their components are analyzed by means of white laser light and differentiated according to structural features. Changes in human cells can be caused by environmental influences such as toxins or harmful substances, the administration of drugs or the use of cosmetics. Early detection of possible cell damage is particularly beneficial for product tests in the pharmaceutical and cosmetics industries.

About the Application Center for Surface Technologies and Optical Metrology AZOM

The Fraunhofer Institute for Material and Beam Technology IWS operates the Fraunhofer Application Center for Optical Metrology and Surface Technologies (AZOM) in cooperation with the University of Applied Sciences Zwickau (WHZ). The scientists are researching and developing the latest approaches in optical metrology, image processing, process control and surface characterization. They strive to transfer research results quickly and directly into application-specific solutions for industrial processes. AZOM provides an interface between applied science and industry in the fields of medical technology, automotive engineering, mechanical engineering and semiconductor technology.

About the University of Applied Sciences Zwickau (WHZ)

The West Saxon University of Applied Sciences Zwickau concentrates its research on technology, business and quality of life. About 3 800 students from almost 50 countries are enrolled in eight faculties with about 50 courses of study. The WHZ is particularly successful in applied research.

Projects such as the development of a production service data glasses application, the manufacture of capacitive energy storage devices with extremely high charge carrier density or the project to design an automated plug-in system for electromobile local public transport combine 120 years of tradition in engineering education with the requirements of the future.

Im Focus: Junior scientists at the University of Rostock invent a funnel for light

Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.

The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.

Im Focus: Stem Cells and Nerves Interact in Tissue Regeneration and Cancer Progression

Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.

Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
