Abstract Compact material constructs possessing some degree of built-in intelligence via the exhibition complex functionalities in response to easily deliverable stimuli are highly desirable for material-powered robots. We report here a visible light-driven, dual-responsive cobalt-doped manganese dioxide (Co-MnO 2 ), which exhibits high actuation performance terms speed and power requirement de...

Sprayable stimuli-responsive material coatings represent a new class of detection system which can be quickly implemented to transform surface into color-responsive sensor. In this work, we describe dipicolylamine-terminated diacetylene-containing amphiphile formulation for spray coating on simple paper substrate yield disposable test strips that used detect the presence lead ions in solution. ...

In the middle of 20th century, Paul Rudolph’s design practice light wood residences in Sarasota area was well adapted to local hot and humid subtropical climate. By tracing origin thought climate responsive design, it’s possible realize features early works from heat protection ventilation, sum up strategies construction his for design. Based on characteristics humidity, Rudolph focused innovat...

Specific delivery of therapeutic agents to solid tumors and their bioavailability at the target site are the most clinically important and challenging goals in cancer therapy. Liposomes are promising nanocarriers and have been well investigated for cancer therapy. In spite of preferred accumulation in tumors via the enhanced permeability and retention (EPR) effect, inefficient drug release at t...

Abstract Soft actuators have brought significant advancements to robotics, allowing robots perform a diverse range of tasks across various domains. However, the increased use soft has resulted in negative environmental impacts, including material consumption, waste generation, and energy consumption. To address these challenges, research is increasingly focused on developing sustainable (SSAs) ...

Dextran, a biocompatible, water-soluble polysaccharide, was modified at its hydroxyls with acetal moieties such that it became insoluble in water but freely soluble in common organic solvents enabling its use in the facile preparation of acid-sensitive microparticles. These particles degrade in a pH-dependent manner: FITC-dextran was released with a half-life at 37 degrees C of 10 h at pH 5.0 c...

Biological systems that utilize multiple weak non-covalent interactions and hierarchical assemblies to achieve various bio-functions bring much inspiration for the design of artificial biomaterials. However, it remains a big challenge to correlate underlying biomolecule interactions with macroscopic level of materials, for example, recognizing such weak interaction, further transforming it into...

On reaction of 2,2'-bipyridine with iridium(iii), an "aggregation induced phosphorescence (AIP)" active "rollover" complex, [Ir(PPh3)2(bipy-H)(Cl)(H)] (bipy-H = κ(2)-N,C-2,2'-bipyridine) or [Ir(bipy-H)], is obtained. The emission colour changes from bluish-green to yellowish-orange and vice versa after repeated protonation and deprotonation of [Ir(bipy-H)], respectively, which unequivocally sup...

The front cover picture shows an image of a unique material platform polymer networks and ionic liquids: Adaptive ion-gel. Recent developments in stimuli-responsive self-healing ion-gels have been highlighted the Review by R. Tamate T. Ueki (DOI: 10.1002/tcr.202300043).

Poly(β-amino ester)s (PBAEs) represent an important class of cationic gene delivery materials which, however, suffer from uncontrolled DNA release due in part to the slow degradation of their polyester backbone. Additionally, PBAEs with high molecular weight (MW) also show considerable toxicities. In this study, we designed and developed PBAEs with trigger-responsive domains built-in polymer ba...
