Plasmonic Chiral Metasurfaces for Real‐Time Refractive Index Sensing and In Situ Monitoring of Thin Film Growth

Small Science, Volume 6, Issue 3, March 2026.
A sensor based on a plasmonic chiral metasurface is fabricated via Layer‐by‐Layer assembly and grazing incidence spraying of silver nanowires, and integrated in a flow‐cell. It enables stable, real‐time circular dichroism measurements with high sensitivity toward refractive index changes of the surroundings.

Ions as Architects of DNA Nanostructures: Mechanisms, Simulations, and Technological Frontiers

Small Structures, Volume 7, Issue 3, March 2026.
Ions are not merely passive electrolytes but active regulators of DNA nanostructures. This review shows how ion valence, hydration, and specificity govern electrostatic screening, correlation, and confinement, enabling DNA origami, metallized DNA, nanopores, hydrogels, DNAzymes, molecular machines, and energy devices through integrated experimental and

Emergence, Challenges, and Opportunities for Chiral Nanocellulose Assemblies in Tissue Engineering and Wound Healing

Small Structures, Volume 7, Issue 3, March 2026.
This review explores chiral nanomaterials for tissue engineering and wound healing, specifically focusing on the potential of nanocellulose. The inherent chirality of nanocelluloses and their assemblies enables the creation of biomimetic scaffolds with unique biological interactions. Chiral nematic self‐assembly of cellulose nanocrystals, in particular,

Control of active nematics

, 2021
Active matter describes systems, such as bacterial suspensions, cellular tissue or cytoskeleton biopolymers, that extract energy from their surroundings at the single-particle level and convert it into mechanical work. The resulting active work can be manifested in the form of self-propulsion and stress generation. The continuous injection of energy or
