  Our latest work has been published in Science Advances. In this study, we introduce an ultrasensitive approach for chemical analysis of airborne particles, combining nanoelectromechanical systems with infrared spectroscopy (NEMS-FTIR). This platform enables simultaneous quantification of key aerosol components with significantly improved detection limits, while offering high time resolution and compatibility with airborne deployment. These results open new perspectives for studying climate-relevant aerosols and their dynamics across diverse environments. This work highlights the importance of close collaboration between the public sector—TU Wien and EPFL— and the private sector, through Invisible Light Labs GmbH, in advancing next-generation sensing technologies.

  We have uploaded a new study to arXiv. In this work, we develop a quantitative framework for on-axis optical transduction of vertical InP nanowire resonators, linking laser position to signal amplitude, calibration, and frequency stability. We show that optimal detection is achieved near the steepest intensity gradient, while increasing laser power does not improve frequency stability due to enhanced thermomechanical noise. These results provide practical design guidelines for optimizing nanowire-based sensors in on-axis optical detection schemes. This work is the result of a collaboration with Lund University and the group of Prof. Borgström.

  Our work on the design optimization of silicon nitride-based infrared (IR) detectors has now been published in AIP Advances. In this comprehensive study, we explore how geometry, tensile stress, and optical properties shape the performance of silicon nitride drumhead and trampoline-based IR detectors. By combining analytical modelling with practical design guidelines, we provide a roadmap for engineering next-generation nanomechanical IR sensors operating near the fundamental detection limit.

  Our new work on a 3D-printed optogenetic light-delivery platform is now available on arXiv. This work has been the result of a close personal collaboration, bringing together expertise in microfabrication, optics, and neuroengineering. In this study, we introduce a highly customizable light-stimulation system for brain organoids, fabricated using projection microstereolithography (PSL). We characterize the optical properties of high-resolution acrylate-based resins and employ finite element simulations to optimize the device design. Initial experiments with optogenetically modified cells show light-induced dopamine release, confirming the functionality of the 3D-printed waveguide and highlighting its potential for advancing next-generation optogenetic tools.
