A nanoscale electrochemical guanine DNA-biosensor based on a flower-like nanocomposite of Tb-doped ZnO for the sensitive determination of pemetrexed

“…have estimated these minor changes in the case of Tb replacing Zn ions in the lattice without any variations in the crystal lattice. 28 Next, FESEM was used for characterization of the morphology of the as-synthesized Tb-doped ZnO nanoowers. Fig.…”

“…For this reason, modifying the bare electrode with transition metal oxides (TMOs) would be preferred for enhancing the electro-active surface area, conductivity, as well as porosity of the materials. [25][26][27][28][29] Since zinc oxide (ZnO) enjoys a higher theoretical specic capacitance (593 F g −1 ), is an n-type semi-conductor material, nontoxic in nature, and has acceptable electrochemical features, which can vary depending on the (spherical/ nonspherical) morphology, composition, and size, it is the most famous compound from among the TMOs that have been investigated to date. 30,31 Doping the host lattice with an appropriate element can offer possibilities for modifying its electronic, chemical (activation energy and catalytic action), and morphological (grain size modications, surface area enhancement) properties, etc.…”

Development of novel microsphere structured – calcium tungstate as efficacious electrocatalyst for the detection of antibiotic drug nitrofurantoin

“…To overcome these limitations, transducer materials are used to fabricate electrodes with an increase in better conductivity and active surface area. 27–29…”

“…To overcome these limitations, transducer materials are used to fabricate electrodes with an increase in better conductivity and active surface area. [27][28][29] The special class of tungstic acid hosts with scheelite crystal structure CaWO 4 with general formula AWO 4 (A = Ca, Sr, Ba, Pb, and Cd) are intriguing in several fields, such as photoluminescence, 30 scintillators, 31 temperature sensing, 32 and catalyst 33 due to their excellent chemical stability and structural characteristics. 34,35 To date, many synthetic strategies have been adapted to obtain distinct chemical activity and shapes of CaWO 4 , including hydrothermal method, 36 the reverse-micelle method, 37 the solid-state reaction, 38 and coprecipitation methods.…”
