Wearable biosensors have emerged as an alternative evolutionary development in the field of healthcare technology due to their potential change conventional medical diagnostics and health monitoring. However, a number critical technological challenges including selectivity, stability (bio)recognition, efficient sample handling, invasiveness, mechanical compliance increase user comfort must still be overcome successfully bring devices closer commercial applications. We introduce integration...
Abstract Traditional thin-film energy-storage devices consist of stacked layers active films on two-dimensional substrates and do not exploit the third dimension. Fully three-dimensional would allow energy storage in bulk materials with arbitrary form factors mechanical properties unique to such as compressibility. Here we show based layer-by-layer self-assembly interdigitated thin surface an open-cell aerogel substrate. We demonstrate a reversibly compressible supercapacitor carbon nanotube...
Step by step: A robust and rapid method for the layer-by-layer assembly of polymers nanoparticles on strong elastic aerogels has been developed. Thin films biomolecules, conducting polymers, carbon nanotubes were assembled, which resulted in with a number functions, including high charge-storage capacity. As service to our authors readers, this journal provides supporting information supplied authors. Such materials are peer reviewed may be re-organized online delivery, but not copy-edited...
Abstract This study presents a novel, green, and efficient way of preparing crosslinked aerogels from cellulose nanofibers (CNFs) alginate using non‐covalent chemistry. new process can ultimately facilitate the fast, continuous, large‐scale production porous, light‐weight materials as it does not require freeze‐drying, supercritical CO 2 drying, or any environmentally harmful crosslinking chemistries. The reported preparation procedure relies solely on successive freezing, solvent‐exchange,...
Chemically cross-linked highly porous nanocellulose aerogels with complex shapes have been prepared using a freeze-linking procedure that avoids common post activation of cross-linking reactions and freeze-drying. The aerogel ranged from simple geometrical three-dimensional bodies to swirls solenoids. This was achieved by molding or extruding periodate oxidized cellulose nanofibril (CNF) dispersion prior chemical in regular freezer reshaping an already plasticizing the structure water...
Spinning filaments from nature's own high-performance building block, cellulose nanofibrils (CNFs), requires additional considerations compared to conventional manmade fibers commonly made polymer solutions or melts. We herein utilize the colloidal properties of highly anisotropic CNFs and demonstrate preparation core–shell using a coaxial nozzle. The nanofibril dispersion is passed through core channel, sheath flow consists functionalizing solution. rates suspensions/solutions are carefully...
Schritt für Schritt: Eine schnelle Methode zur schichtweisen Abscheidung von Polymeren und Nanopartikeln auf starken elastischen Aerogelen wurde entwickelt. Dünne Filme aus Biomolekülen, leitenden oder Kohlenstoffnanoröhren wurden diese Weise abgeschieden, wodurch funktionelle Aerogele mit verbesserten Eigenschaften, einschließlich hoher Ladungsspeicherkapazitäten zugänglich waren.
Model layer-by-layer (LbL) assemblies of poly(allylamine hydrochloride) (PAH) and hyaluronic acid (HA) were fabricated in order to study their wet adhesive behavior. The film characteristics investigated understand the inherent structures during assembly process. Subsequently, adhesion these systems was evaluated correlation between structure energy required separate LbL assemblies. We describe how conditions fabrication can be utilized control films. formation are examined absence presence...
The adhesive characteristics of poly(allylamine hydrochloride) (PAH)/hyaluronic acid (HA) self-assemblies were investigated using contact adhesion testing. Poly(dimethylsiloxane) spheres and silicon wafers coated with layer-by-layer (LbL) assemblies PAH/HA. No increase in was observed when surfaces covered dried LbL films placed contact. However, bringing the while wet separating them after drying resulted an by a factor 100 work (from one to three bilayers). Herein we discuss PAH/HA...
Layer-by-layer (LbL) assembly is a versatile tool for fabricating multilayers with tailorable nanostructures. LbL, however, generally relies on polyelectrolytes, which are mostly insulating and induce large interlayer distances. We demonstrate method in we replace polyelectrolytes the smallest unit capable of LbL self-assembly: molecule multiple positive charges, tris(3-aminopropyl)amine (TAPA), to fabricate films negatively charged single-walled carbon nanotubes (CNTs). TAPA introduces less...
