However, the controlled fabrication of such nanopowders is often cumbersome, especially because their characterization is normally slow, involving procedures such as electron microscopy. On the other hand, microwave sensors based on near-field effects on materials are being developed with high sensitivity and show promising characteristics. In this paper, the authors show how a microwave sensor based on a Square Spiral Resonator can be used to characterize paraffin dispersions of nanoparticles conveniently and cost-effectively. en-GB Revista: Sensors, Periodo: 1, Volumen: online, Número: 9, Página inicial: 2735-1, Página final: 2735-14 Instituto de Investigación Tecnológica (IIT) Measuring sedimentation profiles for nanoparticle characterization through a square spiral resonator sensor info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion info:eu-repo/semantics/openAccess microwave sensors; permittivity; metallic nanoparticles; sedimentation
