Abstract Nanotechnology permits broad advances in agriculture. However, as it is still at a relatively early stage of development, the potential risks remain unclear. Herein, for first time, we reveal following: 1) impact multi-walled carbon nanotubes (MWCNTs) on accumulation/depuration behaviors contaminants crop, mustard ( Brassica juncea ) and 2) permeability transportability MWCNTs intact mature plants. Using an vivo sampling technique, kinetic processes several plans exposed to were...
A novel electrochemical sensor has been developed by using a composite element of three-dimensional (3D) nanoporous nickel (NPNi) and molecularly imprinted polymer (MIP). NPNi is introduced in order to enhance the electron-transport ability surface area sensor, while electrosynthesized MIP layer affords simultaneous identification quantification target molecule employing Fe(CN)63–/4– as probe indicate current intensity. The morphology hybrid film was observed scanning electron microscopy,...
An extensive SAXS investigation of the 3M perfluorinated sulfonic acid ionomer was performed to investigate morphological changes that occur during and after annealing at temperatures above Tα. The effect film thickness in range studied, 11–45 μm, found be negligible. These properties were studied as a function equivalent weight from 700 1100 correlated with water uptake measured by dynamic vapor sorption. Isoscattering points observed experiments unboiled annealed films q = 0.023, 0.096...
In this work, we have developed a nanocomposite consisting of horseradish peroxidase (HRP)-encapsulated 2D Zn-Co zeolite imidazole framework (ZIF) nanosheets strung on ZnCoO nanowire array Ti support (denoted as 2D-Zn/Co-ZIF(HRP)|ZnCoO|Ti). This was then applied to constructing an electrochemical biosensor for detecting H2O2 derived from O2∙- released by mitochondria in living cells. sensing platform shows excellent catalytic performance towards H2O2, attributable the enzyme/metal-catalytic...
A fluorescent self-assembled monolayer film sensor with discriminatory power was specially designed and prepared by using pyrene as a reporting unit oligo(oxyethylene) hydrophilic spacer. The chemical attachment of moieties on the surface verified contact angle, XPS, UV-vis fluorescence measurements. responses present to nitroaromatic compounds (NACs) including picric acid, 2,4,6-trinitrotoluene, 2,4-dinitrotoluene, nitrobenzene were measured. Significantly, exhibits cross-reactive different...
A dansyl-functionalized fluorescent film sensor was specially designed and prepared by assembling dansyl on a glass plate surface via long flexible spacer containing oligo(oxyethylene) amine units. The chemical attachment of moieties the verified contact angle, XPS, fluorescence measurements. Solvent effect examination revealed that polarity-sensitivity retained for surface-confined moieties. Fluorescence quenching studies in water declared SAM possesses higher sensitivity towards Hg(2+)...
Decreasing the tedious sample preparation duration is one of most important concerns for environmental analytical chemistry especially in vivo experiments. However, due to slow mass diffusion paths conventional methods, ultrafast sampling remains challenging. Herein, first time, we report an solid-phase microextraction (SPME) device based on electrosorption enhancement and a novel custom-made CNT@PPY@pNE fiber ionized acidic pharmaceuticals fish. This exhibited excellent robustness,...
The 3M 825EW perfluorosulfonic acid (PFSA) ionomer was doped with the heteropoly acids (HPAs), H3PW12O40 (HPW) and H4SiW12O40 (HSiW). Dynamic vapor sorption measurements at 95% RH showed a decrease in water content as result of HPA doping from λ = 8.05 for undoped ionmer to 4.40 5% HSiW film. FTIR measurement revealed strong interactions between HPAs, ionomer, H2O. Irrespective hydration level, it found that PFSA films tortuous proton diffusion behavior. At maximum 25 °C, self-diffusion...
Nanomaterials have shown great potential for application in microextraction due to their distinguishing nanoscale architectures and superior physicochemical properties.
