An unprecedented high sensitive sensing of neurotransmitter dopamine at fM level was demonstrated using a poly-crystalline silicon nanowire field-effect transistor (poly-SiNW FET) fabricated by employing a simple and low-cost poly-Si sidewall spacer technique, which was compatible with current commercial semiconductor processes for large-scale standard manufacture.

A conjugated-polymer-based n-type yarn for thermoelectric textiles is presented. Thermoelectric textile devices are intriguing power sources wearable electronic devices. The use of yarns comprising conjugated polymers desirable because their potentially superior mechanical properties compared to other materials. While several examples p-type conducting exist, there a lack polymer-based yarns. H...

A micellar assembly of molecules constituted of poly(ethylene glycol) as the hydrophilic component and 2-diazo-1,2-naphthoquinone as the hydrophobic component was shown to be destroyed in a two-photon photoreaction triggered by infrared light with release of an encapsulated fluorescent probe molecule.

We report, for the first time, an in situ formation of two-component hydrogels from pyridine derivatives of poly(aryl ether) dendrons and tartaric acid. The two-component system (dendron + acid) undergoes J-type aggregation, leading to fibrillar type self-assembly in THF-water mixture along with blue (470 nm) and green (500 nm) intrinsic emissions.

In this study, blends of the bio-based poly(limonene carbonate) (PLimC) with different commodity polymers are investigated in order to explore potential PLimC toward generating more sustainable polymer materials by reducing amount petro- or food-based polymers. is employed as minority component blends. Next morphology and thermal properties impact on mechanical matrix studied. The interplay inc...

Natural killer (NK) cells are a component of the innate immunity against viral infections through their rapid cytotoxic activity and cytokine production. Although the synthetic double-stranded (ds) RNA polyinosinic-polycytidylic acid (poly I:C), a mimic of a common product of viral infections, is known to rapidly up-regulate their in vivo functions, NK cell ability to directly respond to dsRNA ...

The nuclei of mammalian cells contain domains, termed nuclear speckles, which are enriched in splicing factors and poly(A) RNA. Although nuclear speckles are thought to represent reservoirs from which splicing factors are recruited to sites of transcription and splicing, the presence of poly(A) RNA in these structures remains enigmatic. An additional component of the speckles is poly(A) binding...

Abstract The present research investigates the hydrolytic degradation of ternary blends composed poly(ethylene- co -vinylacetate) (EVA), poly(lactic acid) (PLA), and poly(styrene- -methyl methacrylate)(poly(S- -MMA) (SMMA) (EPS) at a temperature 37 °C pH 7.4, monitoring changes in phosphate buffer solution for 6 months. In addition, mechanical behavior morphology were evaluated from comparison ...

We have constructed a novel class of "double-hydrophobic" block polypeptides based on the hydrophobic domains found in native elastin, an extracellular matrix protein responsible for the elasticity and resilience of tissues. The block polypeptides comprise proline-rich poly(VPGXG) and glycine-rich poly(VGGVG), both of which dehydrate at higher temperature but form distinct secondary structures,...
