Abstract
A highly sensitive, simple and inexpensive Love-wave gas sensor based on surface functionalized nanoparticles has been developed. A thin film of amine-terminated iron oxide nanoparticles was successfully deposited onto the surface of Love-wave sensor to serve as a gas-sensing layer. A gas sensing test was carried out with N,N-dimetilformamide (DMF), which revealed that the Love wave sensor with surface functionalized nanoparticles has a wide concentration range with very high response, fast response–recovery time and stable repeatability.
