چکیده

Abstract Numerous studies suggest that modification with functional nanomaterials can enhance the electrode electrocatalytic activity, sensitivity, and selectivity of electrochemical sensors. Here, a highly sensitive cost-effective disposable non-enzymatic glucose sensor based on copper(II)/reduced graphene oxide modified screen-printed carbon is demonstrated. Facile fabrication developed sensing electrodes carried out by adsorption copper(II) onto electrode, then following reduction. The proposed illustrates good activity toward oxidation wide linear detection range from 0.10 mM to 12.5 mM, low limit 65 µM, high sensitivity 172 ?A –1 cm –2 along satisfactory anti-interference ability, reproducibility, stability, acceptable recoveries for in human serum sample (95.6–106.4%). superior performances great potential quantitation real samples.

TiO2 based surface acoustic wave gas sensor with modified electrode dimensions for enhanced H2 sensing application

The design and optimization of nanostructure-based surface acoustic wave (SAW) gas sensor is analyzed based on TiO2 sensing layer and modified electrode dimensions. The sensitivity of the gas sensor depends upon the type of sensing layer used and active surface area obtained by varying the aspect ratio. The performance of the sensor is observed from 0.1ppm to 100ppm concentration of ...
