Towards future lab-on-chip applications


Fraunhofer FEP presents latest approaches to fabricate OLED devices for lab-on-a-chip-applications using either near UV electroluminescence (EL) or optically modulated green light to stimulate fluorescent dye markers.

Smart and portable medical equipment is essential for fast and easy point-of-care and point-of-use diagnostics. Lab-on-a-chip applications in hand-held devices can help to save time for laboratory medical analysis in emergency scenarios.


The combination of sub-micrometer-thick light emitting devices and photo-detectors with tunable spectral characteristics could play a key role in future sensing chips based on organic electronics.

These applications realize the excitation and detection of fluorescence or phosphorescence in a marker. Even time-resolved measurements are possible. The integration of both, OLED together with organic photodiodes into one chip could be a way to achieve low-cost personal diagnostics outside the laboratory.

At IDW 2014 Fraunhofer FEP presents two different OLED-device concepts: one emitting in the near UV and another one in the green spectral range which both could be integrated to sensor applications.

These two exemplary OLED developments can be used for biomedical and biotechnical sensing in lab-on-chip applications. Near ultra-violet emission from an OLED is demonstrated for bottom- as well as from top-emitting device architectures.

Furthermore, the scientists from Fraunhofer FEP combined a green top-emitting OLED with a thin-film optical filter and thin-film encapsulation so that a sample substance can be brought in proximity to the excitation source. Both developed devices are suitable for large area deposition and integration on silicon-backplanes like wafers as light source for optical excitation to detect fluorescence or phosphorescence signals.

Dr. Michael Thomschke, project leader at Fraunhofer FEP states: “These developments could be incorporated in very small ultra-thin organic devices based on glass, foil or opaque silicon-backplanes. The integration e.g. on silicon-wafers could be very cost-efficient. The corresponding processes allow large area manufacturing as well as devices in the µm scale.”

Later on, such device could be extended with microfluidics or external optics to fit a certain application.

Next to the results for for OLED applications using UV-electroluminescence, Fraunhofer FEP will also present further demonstrators of our latest OLED microdisplays and flexible OLED on different substrates at our booth during the conference.

Besides the exhibition Dr. Michael Thomschke will give a talk „OLED on Silicon for Sensor Applications“ about the latest approaches of OLED devices for lab-on-a-chip applications on Wednesday, December 3, 15:45 – 16:05 in Snow Hall B.

About Fraunhofer FEP:

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP works on innovative solutions in the fields of vacuum coating, surface treatment and processing with electrons and plasmas as well as organic semiconductors. The core competences electron-beam technology, sputtering and plasma-activated as well as PECVD high-rate coating, technologies for the organic electronic and IC/system design provide the basis for these activities.

Thus Fraunhofer FEP offers a wide range of possibilities for research, development and pilot fabrication, especially for the processing, sterilization, structuring and refining of surfaces as well as OLED microdisplays, organic and inorganic sensors, optical filters and flexible OLED lighting.

Our aim is to develop the innovation potential of the electron beam, plasma technology and organic electronic for new production processes and devices and to make it available for our customers.

Formerly COMEDD (Center for Organics, Materials and Electronic Devices Dresden) with all known activities in organic electronics now is acting as new business units at Fraunhofer FEP, Dresden, Germany.

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
