Three-dimensional flexible porous conductors have significantly advanced wearable sensors and stretchable devices because of their specific high surface area. Dip coating polymers with graphene is a facile, low cost, scalable approach to integrate conductive layers the polymer substrate platforms; however, products often suffer from nanoparticle delamination overtime decay. Here, fabrication scheme based on accessible methods safe materials introduced surface-dope silicone nanoplatelets. The...
Addition of molecular cross-links to polymers increases mechanical strength and improves corrosion resistance. However, it remains challenging install in low-functionality macromolecules a well-controlled manner. Typically, high-energy processes are required generate highly reactive radicals situ, allowing only limited control over the degree type cross-link. We rationally designed bis-diazirine molecule whose decomposition into carbenes under mild controllable conditions enables...
Superparamagnetic iron oxide nanoparticles (SPION) with narrow size distribution and stabilized by polyvinyl alcohol (PVA) were synthesized. The particles prepared a coprecipitation technique using ferric ferrous salts molar Fe3+/Fe2+ ratio of 2. Using design experiments (DOE) approach, the effect different synthesis parameters (stirring rate base molarity) on structure, morphology, saturation magnetization, purity, size, synthesized magnetite was studied various analysis techniques...
We aimed to investigate the physicochemical effects of superparamagnetic iron oxide nanoparticles (SPIONs) on composition protein corona and their correspondence toxicological issues.SPIONs different sizes surface charges were exposed fetal bovine serum. The structure/composition biological corona-SPION complexes probed.The affinity level adsorption specific proteins is strongly dependent size charge SPIONs. In vivo experiments mouse blood-brain barrier model revealed that nontargeted SPIONs...
Abstract This study presents a low‐cost, tunable, and stretchable sensor fabricated based on spandex (SpX) yarns coated with graphene nanoplatelets (GnP) through dip‐coating process. The SpX/GnP is wrapped into silicone rubber (SR) sheath to protect the conductive layer against harsh conditions, which allows for fabricating washable wearable sensors. Dip‐coating parameters are optimized obtain maximum GnP coating rate. covering tailored achieve high stretchability beyond sensing limit of...
Laser additive manufacturing has led to a paradigm shift in the design of next-generation customized porous implants aiming integrate better with surrounding bone. However, conflicting criteria have limited development fully functional implants; increasing porosity improves body fluid/cell-laden prepolymer permeability at expense compromising mechanical stability. Here, functionally gradient and scaffolds designed based on interconnected triply periodic minimal surfaces (TPMS) are...
Abstract Modern materials science has witnessed the era of advanced fabrication methods to engineer functionality from nano‐ macroscales. Versatile and additive manufacturing are developed, but ability design a material for given application is still limited. Here, novel strategy that enables target‐oriented ultra‐lightweight aerogels with on‐demand characteristics introduced. The process relies on controllable liquid templating through interfacial complexation generate tunable,...
As the use of superparamagnetic iron oxide nanoparticles (SPION) in biomedical applications increases (e.g. for targeting drug delivery and imaging), patients are likely to be exposed products containing SPION. Despite their high importance, toxicity data SPION limited date. The aim this study is investigate cytotoxicity its ability change cell medium components. Bare poly(ethylene glycol)-co-fumarate (PEGF)-coated with narrow size distributions were synthesized. particles prepared by...
This study investigated the behavior of ferrofluids containing superparamagnetic iron oxide nanoparticles (SPION) various compositions for potential applications in drug delivery and imaging. To ensure biocompatibility, interaction these SPION with two cell lines (adhesive suspended) was also using an MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The studied were primary mouse connective tissue cells (adhesive) human leukemia (suspended). synthesized a...
