Monitoring and detecting carbon monoxide (CO) are critical because this gas is toxic and
harmful to the ecosystem. In this respect, designing high-performance gas sensors for CO …

Detecting methane (CH4) at room temperature through adsorption-based sensing poses a
challenge due to its inert properties. In this study, we enhance both the sensitivity and …

An oscillating piezoresistive microcantilever (MC) coated with an aluminum (Al)-doped zinc
oxide (ZnO) nanorods was used to detect carbon monoxide (CO) in air at room temperature …

Biodiesel has become an alternative fuel to substitute conventional fuel, yet challenges
remain, particularly concerning water content. The presence of water in biodiesel can …

Surface plasmon resonance (SPR) has been extensively used as a diagnostic tool for virus
and bacteria detection (biosensors). This research detected dengue virus (DENV) using a …

Microcantilever is a device of MEMS (microelectro-mechanical system) which can be used
as a bio-chemical sensor, such as to determine the characteristics of chemical liquids. In this …

A highly sensitive (at the picogram order) Al-doped-ZnO nanorods (AZNRs)-coated resonant
microcantilever (MC) for carbon monoxide (CO) gas sensing, operable at ambient …

Conductivity-based sensor using interdigitated electrode (IDE) as a substrate has been
studied by scientists due to its potential application for sensing devices. Synthesis of zinc …

A frequency sweeper and resonant frequency tracer have been developed to detect the
resonant frequency on the microcantilever sensor. Frequency sweepers and frequency …

Pure and cerium oxide (CeO2)-doped zinc oxide (ZnO) rods have been successfully grown
on glass substrates using hydrothermal method. Growth of ZnO nanorods has two main …
