This article reviews the mutual empowerment between artificial intelligence and metasurfaces, characterizing that artificial intelligence enables intelligent nanophotonics, while metasurfaces facilitate optical intelligence.
A new silicon metasurface capable of rapidly controlling wide-bandwidth light pulses could help advance compact technologies for optical communications, computing, LiDAR and photonic information processing.
A pixel-controlled programmable metasurface capable of dynamically reshaping terahertz (THz) waves could open new possibilities for compact imaging, communications and optical systems.
A Nature Communications review maps how crystal symmetry, material synthesis, and structural control shape polaritons in two-dimensional metal oxides, a diverse family of materials with optical responses spanning the visible to terahertz range. The authors assess fabrication challenges and propose photonic-chip concepts involving reconfigurable waveguides, polariton logic, biosensing, photodetection, and thermal management.
Researchers showed that an ultrathin, nanolayered boron nitride interlayer can improve the stability of perovskite quantum dot LEDs by passivating defects, suppressing ion migration, and enhancing heat dissipation. BN-optimized devices achieved an average peak EQE of 30.05% and a measured T50 lifetime of 102 hours at 2,000 cd m-2, with accelerated testing projecting a T50 of 25,263 hours at 100 cd m-2.
PI introduces the P-606.1P piezoelectric micro gripper, a compact, high-stiffness gripping solution designed for handling micro-optics and FAUs in photonics alignment, assembly, probing, and inspection applications.
A review published in Advanced Materials examines the emerging field of smelltronics, which combines advanced sensing materials, engineered interfaces, sensor arrays, and computational methods to detect and distinguish information-rich volatile organic compounds. The authors highlight how molecular recognition, device integration, machine learning, and improved sensor stability could help translate digital odor sensing into applications spanning healthcare, food monitoring, environmental sensing, and security.
Researchers developed a solid-phase-synthesized nanoMIP sensor integrated with surface plasmon resonance for rapid, label-free detection of bisphenol A in water. The platform detected BPA across 5 to 800 nM with a 1.46 nM detection limit and was validated using LC-MS and commercial drinking-water samples.
Researchers developed a multilayer MCOF@Au@PEI nanomaterial that captures bacteria, converts near-infrared light into heat, and can be magnetically recovered and reused after treatment. In laboratory tests, the material achieved complete plate-count sterilization of E. coli, S. aureus, and S. typhimurium in experimentally contaminated milk and drinking water within 435 seconds, while also disrupting established biofilms.
PI (Physik Instrumente), a global leader in precision motion control and nanopositioning technology, offers the P-733 XYZ piezo nanopositioning stage, delivering 0.1 nm (1 Å) positioning resolution for demanding applications in super-resolution microscopy, atomic force microscopy (AFM), surface nanometrology, and advanced imaging.
