Antibodies on the surface of the sensor specifically trap the biomarker of interest from a sample.
Avidin binds with high affinity to biotin, and so the magnetic nanoparticles become strongly linked to the biomarker antibody complexes on the surface of the sensor.
MIS and NIS were deposited on the surface of the sensor by spin coating.
By utilizing thermal evaporation process, interdigitated electrodes of gold were deposited on the surface of the sensor substrates.
Anti-HBsAg monoclonal antibody is adhered to the surface of the sensor chip by a bifunctional cross-linker with the technology of self-assembly.
The sensing surface of the sensor consists of oxygen sensitive fluorescent dyes (platinum II) octaethylporphyrinketone) embedded in a thin polystyrene film.
In 3D detectors the electrodes are processed not just at the surface of the sensor, but they extend partly or completely through the silicon bulk.
The purpose of this nanostructuration was to modify the topography of the surface and improve the accessibility of the binding sites on the surface of the sensor chips.
The capacitance of the AgNW tandem compound electrode pattern grew via fringing, which increased with the pressure-induced bending applied to the surface of the sensor.
Besides, Au nanoparticles (AuNPs) were directly assembled onto the surface of the sensor chip via hexanedithiol (HDT) for the enhancement of sensitivity as a label-free detection system.
The first configuration is actuated using a piezoelectric stack embedded under the sensor base yielding a base-type actuation while the second is actuated via a piezoelectric ZnO layer deposited on the surface of the sensor.
