Still time to register for Malte's discussion with the Optica editors on #biophotonics, #microlasers and organic #electronics (this week Friday).

A three panel figure showing microlaser characteristics during dynamic compression by an atomic force microscope. (a) Lasing spectra acquired during a push and release experiment, where the force applied by the AFM onto the microlaser is linearly increased from 0 nN to 7 nN and then released back to 0 nN. The spectra are normalized and vertically offset to show the shift and broadening of the lasing modes. (b) Fitted center position of the lasing modes labelled in (a), plotted over the time of the experiment. Two time points right after the microlaser made contact with the beaded tip of the AFM are excluded from the plot due to strong mode splitting. (c) Fitted FWHM (symbols, left axis) of the 4 laser modes shown in (b) and the measured applied force (pink solid line, right axis) as function of time. The resolution limit of the spectrometer is about 50 pm.

Very happy to finalize a few projects after a busy year, starting with a pre-print of Melisa's work on #flexible #microlasers made from #elastomers! A great material to prepare soft microlasers to measure biological #forces. #biophotonics #biosensing arxiv.org/abs/2512.22707

Overview image, showing different microlaser platforms at the top (including disks, spheres, nanorods, and optoplasmonic lasers), the biological targets (cells, organoids, tissue, animals) in the middle, and different applications of microlasers (sensors, optical barcodes, cell tracking) at the bottom.

Is anyone still reading review papers these days? For those who do, check out our #review (open access) on #biointegrated #microlasers, now published in @optica.org. doi.org/10.1364/OPTI...

DNA Sensing with Whispering Gallery Mode Microlasers Nucleic 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.

Good time for a re-post of Vera's @veratitze.bsky.social paper on integrating an ultrafast spectrometer (100k spectra per second!) into custom-built and commercial confocal microscopes. Plus demonstration of our intracellular #microlasers for single cell #tracking and #sensing.
