Engineering In Vitro Models of Skeletal Muscle With Neuromuscular Junctions Using Hierarchical Micro‐Nano Biomaterials: Cooperative Effect of Adhesion Ligand Nanoclustering and Surface Anisotropy

open access: yesSmall, EarlyView.
This study investigates the cooperative effects of adhesive ligand distribution, density, and biomaterial morphology for innervated skeletal muscle tissue engineering. Ligand nanoclusters were created in aligned micropatterns by electrospinning of a RAFT‐synthesized polymer with controlled ligand presentation.

NanoDMA and Nanoscratch Study of (Visco)‐Elastic and Plastic Behaviors of a Thin Film of a Molecular Spin Crossover Complex

open access: yesSmall, EarlyView.
Thin films of a molecular spin crossover complex are investigated across its thermally induced spin transition using quasi‐static and dynamic indentation techniques as well as nanoscratch experiments. When going from the low‐spin to the high‐spin state a sudden drop of elastic modulus is observed, but only a weak modulus relaxation occurs at the ...

Mechano‐Chemical Coordination of Nanoparticle‐Based Artificial Antigen‐Presenting Cells Synergistically Tunes T Cell Activation and Expansion Phenotypes

open access: yesSmall, EarlyView.
Mechanically distinct nano artificial antigen‐presenting cells with independently controlled antibody density are used to reveal how physical and biochemical cues jointly regulate human T‐cell activation. Increasing stiffness and antibody density accelerates activation, enhances expansion, and promotes effector‐associated differentiation, whereas ...

Morphological Stabilization of CsPbBr3 Quantum Dot Films Enabled by PVC‐g‐PMMA Graft Copolymer Encapsulation for Water‐Robust Color Conversion

open access: yesSmall, EarlyView.
Poly(vinyl chloride)‐graft‐poly(methyl methacrylate) encapsulation enabled formation of water‐stable CsPbBr3‐quantum‐dot fims with enhanced photoluminescence (PL) retention upon exposure to water, UV radiation, and ethanol. Time‐dependent ex situ transmission electron microscopy with quantitative particle segmentation identified the coefficient of ...

Multi‐Scale 3D Printing of Magnetic Polymer Nanocomposites with Controlled Particle Dispersion and Hyperthermic Response

open access: yesSmall, EarlyView.
Dispersion of magnetic nanoflowers in trimethylolpropane ethoxylate triacrylate to generate photocurable nanocomposites is described. Particle dispersion provides processability and target AC‐field stimulated temperature increases. Complex (DLP) printed structures with submicron features are demonstrated, and the potential for stimulated release of ...

NaCl‐Templated Iron Sulfide/N‐Doped Carbon Microspheres for High‐Performance Sodium‐Ion Batteries: From Nanostructural Design to Pouch Cells

open access: yesSmall, EarlyView.
NaCl‐templated FeS microspheres with a conformal N‐doped carbon coating are synthesized via scalable spray pyrolysis and subsequent surface engineering. The interconnected porous framework accelerates Na+ transport and alleviates structural degradation during cycling. Benefiting from enhanced electrochemical kinetics and mechanical robustness, FeS‐NaCl@

Endocytosis‐independent cytosolic entry of messenger RNA via fluorous bilayer zippering attenuating Toll‐like receptor signaling and enables ischemic tissue salvage

open access: yesSmart Molecules, EarlyView.
The present study establishes a paradigm shift in synthetic mRNA delivery through the convergence of three orthogonal chemistries—perfluoro‐acylation, bio‐orthogonal click cross‐linking, and disulfide reduction—within a single, modular polymer architecture. Abstract A fundamental constraint of conventional messenger RNA (mRNA) delivery systems is their
