Herein, we report for the first time a biocompatible cross-linked trianglamine (Δ) network efficient iodine removal from vapor phase, water, and seawater. In could capture 6 g g-1 of iodine, ranking among most performant materials capture. liquid this is also capable capturing at high rates aqueous media (water seawater). This displayed fast adsorption kinetics, they are fully recyclable. study reveals affinity intrinsic cavity trianglamine. The synthesized extremely interesting since...
In nature, aquaporins (AQPs) are proteins known for fast water transport through the membrane of living cells. Artificial channels (AWCs) synthetic counterparts with intrinsic permeability have been developed hope mimicking performances and natural functions AQPs. Highly selective AWCs needed, design selectivity filters is tremendous importance. Herein, we report use self-assembled trianglamine macrocycles acting as in lipid bilayer membranes that able to steric restriction along biomimetic...
Towards a versatile and easy method of elaboration solid polymeric antimicrobial materials.
Per- and polyfluoroalkyl substances (PFAS) are now a paramount concern in water remediation. Nowadays, urgent action is required for the development of advanced technologies aimed at capturing PFAS mitigating their impact. To offer solution, functional 3D printed hydrogel tailored designed to trap broad spectrum contaminants. The made photo-crosslinked dimethacrylate-ureido-trianglamine (DMU-Δ) Pluronic P123 dimethacrylate (PDM) fabricated by stereolithography (SLA). With aid 3D-printing,...
4D printed hydrogels have been generated by DLP, using resins composed of two distinct thermosensitive copolymers (poly(oxazoline) and poly(acrylamide)) exhibit remarkable volume morphing capabilities with temperature modulation.
The development of hydrogel materials in additive manufacturing displaying stiff and strong mechanical properties while maintaining high water uptake remains a great challenge. Taking advantage the versatility poly(oxazoline) (POx) chemistry properties, we investigated this article new generation POx hydrogels fabricated by stereolithography (SLA). A large range photosensitive poly(2-methyl-2-oxazoline) resins were synthesized as precursors for SLA photofabrication. Functionalization has...
In this work, we report on the synthesis and investigation of new hybrid multifunctional iron oxide nanoparticles (IONPs) coated by coumarin-bound copolymer, which combine magneto- or photothermal heating with luminescent thermometry. A series amphiphilic block copolymers, including Coum-C11-PPhOx27-PMOx59 Coum-C11-PButOx8-PMOx42 bearing photodimerizable coumarin moiety, as well coumarin-free PPhOx27-PMOx57, were evaluated for their utility thermometers encapsulating spherical 26 nm IONPs....
Due to the increasing challenges posed by growing immunity poly(ethylene glycol) (PEG), there is interest in innovative polymer-based materials as viable alternatives. In this study, advantages of lipids and polymers are combined allow efficient rapid cytoplasmic drug delivery. Specifically, poly(2-methyl-2-oxazoline) modified with a cholesteryl hemisuccinate group lipid anchor (CHEMSPOx). The CHEMSPOx additionally functionalized coumarin (CHEMSPOx-coumarin). Both self-assembled water into...
Abstract Vertically oriented nanoporous cylinders, demonstrating an unprecedented alignment persistence, were produced within freestanding poly(1,1‐dimethyl silacyclobutane)‐ block ‐polystyrene‐ ‐poly(2‐vinyl pyridine) (PDMSB‐ b ‐PS‐ ‐P2VP) layers (~15 μm thick) blended with short PS‐ ‐P2VP chains by combining the non‐solvent induced phase separation (NIPS) process a solvent vapor annealing (SVA) treatment. Here, NIPS step allowed for formation of asymmetric and porous PDMSB‐ film having top...
In the nanomedicine field, there is a need to widen availability of nanovectors compensate for increasingly reported side effects poly(ethene glycol). Nanovectors enabling cross-linking can further optimize drug delivery. Cross-linkable polyoxazolines are therefore relevant candidates address these two points. Here we present synthesis coumarin-functionalized poly(2-alkyl-2-oxazoline) block copolymers, namely, poly(2-methyl-2-oxazoline)-block-poly(2-phenyl-2-oxazoline) and...
