Optical sensing of biological #forces with #microlasers, now published in @opg.optica.org. Data from Melisa's master thesis, with additional cell data measured by David. So great to have a solid+soft material as alternative to oil droplet microlasers. doi.org/10.1364/OME.... (open access)

A monochrome sketch of a dense layer of biological cells. One cell is shown with more details, including different organelles. The cell also contains a spherical bead that emits a green glow. Red lines and arrows around the bead indicate the biological force that deforms the bead and changes the spectrum of the emitted light from which the absolute force is calculated.

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

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.

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...

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.

Very happy to contribute to #BIOspektrum! My short (3 pages) take on the applications and potential of #microlasers for #biosensing and #singlecell tracking. Open access👉 rdcu.be/elhkx (in German) Thanks @gbmev.bsky.social, @gesvirologie.bsky.social and @riemerlab.bsky.social 😉 for the invitation!
