Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Advancing Machine Learning Optimization of Chiral Photonic Metasurface: Comparative Study of Neural Network and Genetic Algorithm Approaches

Advanced Physics Research, Volume 5, Issue 6, June 2026.
Two methods for the optimization of chiral reflection by a metamaterial made of either GaP/Air or PMMA/Air interfaces are compared, showing approaches towards fast design exploration and high‐performance results: a neural‐network pipeline and a genetic algorithm. The structures considered are characterized by a periodic, chiral texturation with a shape

Raman Spectroscopy–Based Glucose Feed Control Automates Malic Acid Fermentation

Biotechnology and Bioengineering, Volume 123, Issue 6, Page 1721-1732, June 2026.
Raman spectroscopy enables automated, closed‐loop glucose feeding for malic acid production with Ustilago trichophora. Online PLS regression of glucose and malic acid provides input for PID control to maintain 20 g/L glucose. The feed is dynamically adjusted and stopped in response to metabolic demand and product inhibition, demonstrating practical ...

Using Principal Components Analysis to Visualize Motion and Mitigate Artifacts in Dynamic Optical Coherence Tomography

Journal of Biophotonics, Volume 19, Issue 6, June 2026.
We demonstrate that Principal Component Analysis (PCA) can be used in dynamic OCT to substantially reduce artifacts from strong specular reflections, isolate movement within the sample, and create thin, histology‐like images, thereby avoiding the need for complex, time‐consuming techniques used in clinical histopathology.
