Electrochemical aptamer-based sensors enable real-time molecular measurements in the living body. The spatial resolution of these and ability to perform targeted locations, however, is limited by length width device's working electrode. Historically, achieving good signal noise complex, noisy vivo environment has required electrode lengths 3–6 mm. To sensor miniaturization, here we have enhanced signaling current obtained for a given macroscopic dimensions increasing its surface area....
Abstract The electrochemical reduction of CO 2 to useful chemicals and fuels has garnered a keen broad interest. Herein, we report unique nanocomposite consisting Cu nanoparticles (NPs) reduced graphene oxide (rGO) supported on substrate with high catalytic activity for reduction. was optimized in terms the composition NPs rGO as well overall amount. A gas chromatograph employed analyze gaseous products, whereas chemical oxygen demand (COD) method proposed utilized quantify liquid products....
Abstract Electrochemical CO 2 reduction technology could solve the -induced climate warming by electrochemically converting atmospheric back into fuel, essentially recycling it and building a low carbon emission economy. However, electrochemical reaction (CO RR) poses significant challenge due to highly stable linear molecules, in addition proton-coupled multi-electron transfer process. Thus, active catalysts, placed on activity bolstering materials, permeable electrodes are crucial for RR....

Abstract Nanostructured CuWO 4 photoanodes were fabricated through a facile electrodeposition method, which was followed by annealing the sample at 500 °C for 2 h. The morphologies, crystalline structure, electronic states, optical behaviors, and photoelectrochemical characteristics of nanomaterial examined scanning electron microscopy, X‐ray diffraction, photoelectron spectroscopy, UV/Vis impedance showing that formed triclinic nanoparticles had an indirect band gap 2.2 eV strong response...
Herein, we report on the facile synthesis of nanocomposite consisting TiO2 and Au nanoparticles (NPs) via a tailored galvanic replacement reaction (GRR). The electrocatalytic activity synthesized TiO2/Au nanocomposites for CO2 reduction was investigated in an aqueous solution using various electrochemical methods. Our results demonstrated that formed through GRR process exhibited improved catalytic activities reduction, while generating more hydrocarbon molecules than typical formation CO...

Abstract Herein, the consecutive incorporation of Ag I ion into dsDNA containing adjacent C−C mispairs is demonstrated. The melting temperature (T m ) was 8 ° C higher for DNA three upon addition ions as compared to ‐free DNA, and no T obtained in presence excess ion, indicating a stable bridging C‐Ag −C stoichiometric amount per mispair. circular dichroism (CD) spectra showed negative peak at ∼270 nm , implying that significant structural changes potential aggregation occurred....
