Ultra‐Broadband Optical Characterization of TiO2 Nanotube Arrays Revealing Annealing‐Tunable THz Absorption

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Lithography‐free spaced TiO2 NT arrays unlock tunable broadband absorption from THz to UV. By harnessing annealing‐driven phase transitions, strong phonon–polariton resonances emerge in the 1.4–3.6 THz range, whereas high absorptance persists beyond 10 THz.

Reciprocal Asymmetric Transmission in Directionally Metallized Silica Nanogratings With Broken Lateral Mirror Symmetry

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Directional silver coating breaks lateral mirror symmetry in a reciprocal silica nanograting. Opposite in‐plane illumination directions redistribute optical power differently among diffraction and absorption channels, producing strong polarization‐preserving lateral transmission contrast.

Linking Device Performance to Nanoscale Photoactivation of Grain Boundaries in 2D Hybrid Halide Perovskites

Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.
The opto‐electronic response of polycrystalline (PEA)2PbBr4 thin films is investigated by correlating macroscopic photodetector performance with nanoscale mapping techniques. Grain boundary density is systematically tuned through crystallization control and linked to device responsivity.

Edge‐Grafted Polyarginine Functionalization of Graphene Nanocarriers Maintains Noncovalent Aromatic Drug Loading

Journal of Peptide Science, Volume 32, Issue 8, August 2026.
Edge‐selective covalent grafting of poly‐arginine‐11 onto B60 graphene nanoparticles preserves the aromatic basal plane for π‐π immobilization of compound 8, highlighting this promising NEK6 inhibitor as the key therapeutic cargo in a peptide‐graphene nanoplatform for potential delivery.

An Integrated Micromirror System for High‐Throughput Multi‐Parametric Cell Imaging

Small Methods, Volume 10, Issue 15, 7 August 2026.
A sheathless optofluidic platform integrates 3D‐printed micromirrors for simultaneous brightfield and dual‐color fluorescence imaging. Leveraging two‐photon stereolithography for rapid, single‐step fabrication, the system enables high‐content intracellular mapping and translocation analysis at throughputs exceeding 3000 cells per second.
