Glucose Sensors Based on Chitosan Capped ZnS Doped Mn Nanomaterials
نویسندگان
چکیده
A typical glucose sensor is a oxidase (GOx) enzyme-based due to its high sensitivity and selectivity. However, it has difficulty activating stabilizing the enzyme. To enhance stability of GOx-based sensors, chitosan added ZnS-doped Mn nanoparticles. Chitosan stabilizes particles can induce charge processes such as creation, transfer, separation at polymer interface nanoparticles' interface. Hence, strong candidate for electrochemical sensing applications. This letter reports impedance biosensor based on Mn-capped nanomaterials microinterdigitated electrodes. The sensors' sensitivity, accuracy, are obtained in range 2 10 mM. In addition, an application Canny edge detection limit demonstrated using experimental data.

Mn-doped ZnS nanoparticles as efficient low-voltage cathodoluminescent phosphors
We have synthesized nanoparticles of ZnS doped with Mn for potential use as cathodoluminescent phosphors in field-emission displays ~FEDs!. We show that the cathodoluminescent efficiency of particles <100 nm in diameter is within 40% of that of a commercial ~micron-sized! phosphor when the electron-beam energy ranges between 500 and 3500 eV. The nanoparticles exhibit less current saturation tha...
متن کاملCTAB-capped Mn-doped ZnS quantum dots and label-free aptamer for room-temperature phosphorescence detection of mercury ions.
A new room-temperature phosphorescence (RTP) mercury ions sensor has been developed based on cetyltrimethylammonium bromide-capped Mn-doped ZnS quantum dots (CTAB/Mn-ZnS QDs) and label-free thymine (T)-rich aptamer. The formed T-Hg(2+)-T dsDNA can linearly quench the RTP of Mn-ZnS QDs through electron transfer and aggregation effect, and give a detection limit of 1.5 nM.
متن کاملChitosan capped Silver nanoparticles used as Pressure sensors
In the present work, we report the synthesis and characterization of silver nanoparticles, capped with chitosan (biopolymer ). The majority of the particles produced in this way had sizes around 18 nm. Composite films of capped silver nanoparticles and chitosan polymer were studied to understand the charge transport under different pressure. Films of different compositions were prepared to meas...
متن کاملWater-based route to colloidal Mn-doped ZnSe and core/shell ZnSe/ZnS quantum dots.
Relatively monodisperse and highly luminescent Mn(2+)-doped zinc blende ZnSe nanocrystals were synthesized in aqueous solution at 100 °C using the nucleation-doping strategy. The effects of the experimental conditions and of the ligand on the synthesis of nanocrystals were investigated systematically. It was found that there were significant effects of molar ratio of precursors and heating time...

Mesoporous ZnS-NiS composites are prepared via ion- exchange reactions using ZnS as the precursor. The prepared mesoporous ZnS-NiS composite materials have large surface areas (137.9 m(2) g(-1)) compared with the ZnS precursor. More importantly, the application of these mesoporous ZnS-NiS composites as nonenzymatic glucose sensors was successfully explored. Electrochemical sensors based on meso...
