The fabricated sample is shown in Fig. 5.
(a) Overall view of the fabricated sample.
Glucose determination in human blood serum sample was performed using the fabricated sensing system.
Furthermore, an energy dispersive spectroscope (EDS) (7593-H, HORIBA, Japan) was used to analyze the composition of the fabricated samples.
Markers on the fabricated samples were used to identify the same disk in both setups, allowing disks measured in μPL to be subsequently imaged by SEM-CL.
The cytotoxicity of the fabricated samples was investigated using an MTT assay after 7 days of cell culture and found to be negligible (~ 100% viability).
The morphology and structural properties of the fabricated samples were analyzed using a field-emission scanning electron microscope [FE-SEM] (LEO SUPRA 55, Carl Zeiss, Oberkochen, Baden-Württemberg, Germany) with an operating voltage of 15 kV.
The magnetic behavior of the fabricated samples was studied using a VSM in two different magnetic field configurations: parallel (//, ϕ = 0°) and perpendicular (⟂, ϕ = 90°) modes, according to the angle ϕ between the applied field and the NW/NT long axis.
Atomic force microscopy (AFM) was also used to image the surface morphologies of the fabricated samples.
