Femtolitre Volume cryoEM Sample Preparation Using a Force‐Sensitive Microfluidic Cantilever

open access: yesAdvanced Materials Technologies, EarlyView.
Cryogenic electron microscopy enables structural imaging of biological molecules, but current methods lack targeted extraction of subcellular content for direct vitrification. This study introduces a force‐sensitive microfluidic cantilever pipette that aspirates and dispenses femtolitre volumes from individual cells onto electron microscopy grids.

High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

The Influence of the Supporting Substrate on Single‐Particle Circular Differential Scattering of DNA Assembled Nanorod Dimers

open access: yesAdvanced Optical Materials, EarlyView.
For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

High Contrast and High Efficiency Optical Weighting for Integrated Photonic Computing

open access: yesAdvanced Optical Materials, EarlyView.
Herein, a combined pulse optical weighting scheme is proposed for photonic synapses. Employing a 4 μm$\umu{\rm m}$ long non‐volatile phase‐change material covered on a straight waveguide, a transmission contrast of 31.2 dB is achieved. By exploiting the non‐Arrhenius behavior of the material, the crystallization energy is reduced to 107 pJ, with ...

3D Meta‐Atoms for High Confinement of Mid‐IR Radiation

open access: yesAdvanced Optical Materials, EarlyView.
Mid‐infrared, three‐dimensional circuit‐like resonators with extreme field confinement are experimentally demonstrated. Combining simulations, measurements, and analytical modelling, a physical interpretation and prediction of the resonant modes supported by the structure, including their resonant frequency and radiative and non‐radiative losses, is ...
