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

Advanced Science, Volume 12, Issue 16, April 24, 2025.
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.

Highly Sensitive Detection of Glucose in the Presence of Serum Based on Signal Amplification of Persistent Luminescence Nanoparticles Functionalized by Glucose Oxidase

Advanced Optical Materials, Volume 13, Issue 4, February 3, 2025.
The persistent luminescence signal of ZnGa2O4:Cr nanoparticles covalently functionalized with glucose oxidase shows a significant increase upon exposure to glucose and under UV excitation. The parameters of the hydrothermal synthesis of ZGO (120 °C for 6, 12, or 24 h) strongly influence their sensitivity to H2O2.

Surface Plasmon Electrochemistry [PDF]

arXiv, 2023
Surface plasmon polaritons (SPPs) are optical waves that propagate along a metal surface. They exhibit properties such as sub-wavelength localization and field enhancement which make them attractive for surface sensing, as commonly encountered in surface plasmon biosensors - the most widespread of all optical biosensors. Electrochemistry also occurs on
