Simultaneous Detection of Neural Activity and Temperature in Photothermal Neural Stimulation

Advanced Science, EarlyView.
Photothermal neuromodulation technology faces limitations in understanding its mechanisms and effects on cellular behavior due to the difficulty of directly measuring temperature changes at the cell interface during optical stimulation of neurons. To overcome this challenge, ultrasensitive, transparent temperature sensors integrated with low‐noise ...

Photosensitivity and Carrier Densities of Perovskite Solar Absorbers

Advanced Science, EarlyView.
A novel analysis of the dark and light I–V curves of perovskite solar cells enables the determination of the charge carrier density, the extraction of the ionicity factor, and the quantification of the gain and loss processes, to name a few. The mechanism causing photosensitivity is attributed to the dissociation/pairing of bipolarons/p‐type large ...

Three‐Channel Wavefront Shaping Using Non‐Interleaved Spin‐Multiplexed Plasmonic Metasurfaces

Advanced Science, EarlyView.
A versatile non‐interleaved plasmonic metasurface platform has been developed using quarter‐wave plate meta‐atoms for independent and simultaneous phase modulation of both co‐ and cross‐polarized circularly polarized waves. Three proof‐of‐concept designs have been validated in the near‐infrared: a beam deflector with three distinct reflection angles, a

High‐Speed Hyperspectral Imaging for Near Infrared Fluorescence and Environmental Monitoring

Advanced Science, EarlyView.
This study introduces a fast hyperspectral imaging method in the near‐infrared range (HyperNIR). Combining tunable polarization optics with a phasor‐based approach, HyperNIR captures detailed spectral information with just three images. The applicability is showcased by distinguishing NIR fluorophores that are separated by 5 nm.
