Our novel technology overcomes the problem of angle-dependence in thin film optical coatings by exploiting the quantum mechanical interaction of light with electronically excited states in thin layers of organic materials, significantly enhancing the performance of a variety of optical systems.

On that occasion I am visiting Display Week to see everything new in the display industry and introduce our newest developments - record efficiency in polariton OLEDs using TADF. Come see me if you're there! Talk today at 12:10 in the OLED devices session.

We are extremely proud to have been awarded an EXIST-Forschungstransfer grant to develop new optical filters based on #organic #polaritons towards market readiness. The new filters will enable new optical applications with higher fields of view, higher range and lower noise in many fields.

Many thanks to all for this great collaboration pushing further the limits of microlasers - this time for DNA sensing. In particular to former #HCNB postdoc @sorayacaixeiro.bsky.social now at UBath and our friends from @kathlab.bsky.social in organic chemistry @chemunicologne.bsky.social.

🧬🔬New paper online: Nucleic acid sensing using DNA-functionalized whispering gallery mode microlasers! Great collaboration with @thegatherlab.bsky.social @sorayacaixeiro @schubertlab.bsky.social @chemunicologne.bsky.social 🧪 #DNASensing #microlasers pubs.acs.org/doi/full/10....

pubs.acs.orgDNA Sensing with Whispering Gallery Mode MicrolasersNucleic acid sensing is crucial for advancing diagnostics, therapeutic monitoring, and molecular biology research by enabling the precise identification of DNA and RNA interactions. Here, we present an innovative sensing platform based on DNA-functionalized whispering gallery mode (WGM) microlasers. By correlating spectral shifts in laser emission to changes in the refractive index, we demonstrate real-time detection of DNA hybridization and structural changes. The addition of gold nanoparticles to the DNA strands significantly enhances sensitivity, and exclusively labeling the sensing strand or a hairpin strand eliminates the need for secondary labeling of the target strand. We further show that ionic strength influences DNA compactness, and we introduce a hairpin-based system as a dual-purpose sensor and controlled release mechanism for drug delivery. This versatile WGM-based platform offers promise for sequence-specific nucleic acid sensing, multiplexed detection, and in vivo applications in diagnostics and cellular research.

Hello Bluesky! 👋 Here, I'll post news from our lab at TU Dresden, faculty of electrical and computer engineering. We develop flexible, micropatterned organic LEDs and photodiodes for use in optogenetics and fluorescence imaging. I'm open for scientific exchange. 👩‍🔬
