Towards future lab-on-chip applications

12.11.2014

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.


UV-OLED

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: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
