Dual‐Functionality, Bio‐Friendly Artificial Muscles for Actuation and Motion Sensing in Smart Wearable Systems

open access: yesSmall, EarlyView.
This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

Dual‐Stimuli Responsive Poly(N‐acryloyl glycine) Microgels: Investigation of Network Structures and Application for Loading and Release of Biologics

open access: yesSmall, EarlyView.
Poly(N‐acryloyl glycine) hydrogel microparticles were fabricated via droplet‐based microfluidics and in situ photopolymerization. Rheology and MQ‐NMR revealed pronounced effects of pH and Ca2+ on network constraints and chain mobility, governing extensive swelling.

Mesophase Tunable Actuation of Ionic Thiol‐Acrylate Liquid Crystal Elastomers

open access: yesSmall, EarlyView.
Thiol‐acrylate ionic liquid crystal elastomers (iLCE) are developed with nematic and cybotactic mesophases and polydomain and monodomain genesis. The effect of genesis, mesophase, and microstructure on electroactuation was studied. ABSTRACT Electroactive polymers (EAPs) are envisioned to play a crucial role in next‐generation soft robotics for their ...

Surface‐Functionalized Poly(2‐Oxazoline)‐Based Grids Produced by Two‐Photon Polymerization as 3D‐Structured Hydrogels Promoting Cell Adhesion

open access: yesSmall, EarlyView.
Sidechain‐functionalized poly(2‐oxazoline) cross‐linkers were utilized to print grids with varying mesh sizes by two‐photon polymerization (2PP grids). The amino‐functionalized hydrogels were subsequently used to covalently couple the RGD‐containing peptide sequence GCWRGDSP (RGD) to the amino groups in the side chains. In cell adhesion tests with L929

Engineering Protein‐Polymer Hybrid Multilayer Microreactors as Antioxidant and Anti‐Inflammatory Therapeutics: Effect of Single Enzyme Nanogel Localization Within the Multilayer Systems

open access: yesSmall, EarlyView.
Protein‐based multilayer microreactors combine single‐enzyme nanogels (SENs) and layer‐by‐layer (LbL) assembly to control catalase localization. Positioning the enzyme within the core or at different locations of the multilayer architecture reveals how spatial organization influences antioxidant and anti‐inflammatory activity.

Fluorinated copolymer resists for high‐resolution negative‐tone lithography: Preparation and patterning performance

open access: yesSmart Molecules, EarlyView.
Electron‐beam induced C–F cleavage in –CF3 generates F−, which abstracts a proton to form the acid that catalyzes tBMA deprotection during post‐exposure baking. This self‐sensitization mechanism enables the precise formation of high‐resolution negative‐tone patterns with enhanced sensitivity and resolution.
