Monolithic UV‐Laser Programming of Photothermally Meta‐Morphing SMA Structures: Dual‐Encoded Kirigami Mechanics and Photonic Absorbance

Advanced Science, EarlyView.
A monolithic manufacturing strategy is presented for photothermal shape memory alloy (SMA) meta‐morphing structures. Using a single‐step UV‐laser process, the mechanical compliance is programmed via kirigami patterning while optical absorbance is simultaneously tuned through surface oxidation.

Phototriggered Morphological and Compositional Change of UGGAA Repeat RNA Foci by Photoswitchable RNA‐Binding Ligand

Angewandte Chemie, EarlyView.
We here developed a molecular tool for the optical control of UGGAA repeat RNA foci, a pathological hallmark of spinocerebellar ataxia type 31 (SCA31). The photoswitchable RNA‐binding ligand enabled reversible control of the RNA foci. UV irradiation induced the growth of the RNA foci, while subsequent visible light irradiation dissolved the structure ...

Oxygen‐Acceptor‐Driven High Photochromic Contrast Solid‐State Excited‐State Intramolecular Proton Transfer Photoswitches

Angewandte Chemie, EarlyView.
The excited‐state intramolecular proton transfer (ESIPT) photoswitch tpmSA, which features an oxygen−acceptor, exhibits higher photochromic contrast (ΔE*Lab>74) than its nitrogen‐acceptor Schiff base analogues (ΔE*Lab<30). Theoretical calculations indicate that tpmSA effectively suppresses GSIPT, thereby enhancing the contrast.

Photoresponsive Rotaxanes Switch Lipid Bilayer Neuromorphic Behavior with Light

Advanced Electronic Materials, EarlyView.
A rotaxane consisting of a macrocycle ring with two azobenzene units mechanically interlocked onto an amphiphilic axle was incorporated into droplet interface bilayers (DIBs). Photoswitching between the azobenzene configurations on the ring resulted in cycling between memristive and memcapacitive behaviors in lipid bilayers, enabling programmable ...

Modular Electronic Microrobots With Onboard Sensor‐Program‐Steered Locomotion

Advanced Intelligent Systems, EarlyView.
Modular electronic smartlet microrobots integrate ambient‐light energy harvesting, photodetection, programmable CMOS control, and bubble‐based actuation within a sub‐millimeter fold‐up architecture. A 58‐bit on‐board CMOS chiplet enables sensor–program steered switching between independently addressable actuators, achieving closed‐loop 2D navigation in
