Diatom‐Inspired 1D Immobile Robots Capable of 2D Collective Mobility

Advanced Intelligent Systems, EarlyView.
This study presents a diatom‐inspired robotic system that explores group coordination through limited physical interactions. The researchers tune groups of Barbots, simple robotic agents that possess neither individual mobility nor explicit communication capabilities, to achieve complex and adaptive collaboration based on environmental light.

Selenium Nanomaterials for Wound Healing: Synergistic Strategies from Anti‐Infection to Tissue Regeneration

Advanced NanoBiomed Research, EarlyView.
Selenium nanoparticles (SeNPs) are emerging as multifunctional platforms for wound healing, integrating antimicrobial, anti‐inflammatory, and proregenerative activities. This review summarises key mechanisms and recent advances in SeNP‐enabled composite dressings, immunomodulatory nanocomposites, microenvironment‐responsive hydrogels, photothermal and ...

Intensity noise and modulation dynamics of an epitaxial mid-infrared interband cascade laser on silicon

APL Photonics
Interband cascade lasers typically have significantly lower threshold current and power consumption than quantum cascade lasers. They can also have advantages regarding costs and compactness with the photonic integration onto silicon substrates by ...

Mimicking a Light‐Harvesting Complex to Accelerate Photooxidation in Asymmetric Lipid Membrane Nanoreactors

Angewandte Chemie International Edition, EarlyView.
Biomimetic liposome nanoreactors mimicking natural light‐harvesting complexes enable efficient photooxidation of NADH. Membrane‐anchored fluorescein transfers energy via FRET to membrane anchored eosin Y, oxidizing NADH. While symmetric membranes show little improvement, asymmetric chromophore distribution enhances photooxidation rates by up to 27 ...
