The morphology of Se@AM NPs was characterized by transmission electron microscopy (TEM, H-7650). Elemental composition of Se@AM was determined by energy dispersive X-ray spectroscopy (EDX) (EX-250 system; Horiba, Kyoto, Japan). Zeta potential and size distribution of Se@AM were monitored by Malvern Zetasizer (Malvern Instruments Limited, Manchester, UK) software. Fourier-transform infrared spectroscopy samples were recorded using the potassium bromide-disk method (Equinox 55 IR spectrometer). X-ray photoelectron spectroscopy (XPS) measurement was carried out on ESCALab 250 spectrometer.41 (link)

For particle’s elements qualitative and quantitative analysis, energy-dispersive X-ray spectroscopy (EDS) was conducted. β-TCP test and control samples elemental composition analysis were performed using the same SEM. For the surface morphology evaluation, a machine that combines SEM and EDS was used (EX-250 SYSTEM, HORIBA, Kyoto, Japan).

To analyze the surface morphologies of the scaffolds, β-TCP particles treated with argon gas discharge plasma were analyzed and compared with nontreated β-TCP. We used scanning electron microscopy (SEM; EX-250 SYSTEM, HORIBA, Kyoto, Japan) images to observe the microstructure and crystal size of the particles. These images were analyzed using ImageJ version 1.52 (NIH IMAGE, Bethesda, MD, USA). The arithmetical mean value roughness (Ra) was calculated for quantitative analyses.

β-Thujaplicin-modified
selenium nanoparticles were prepared as previously reported.36 (link) Stock solution of Na2SeO3 (0.25 mL, 0.1 M) was gradually added into 2 mL stock solution (50
mM) of vitamin C. Then, 10 μL 40 mg/mL of β-thujaplicin
was added into the selenium nanoparticle solution. The excess β-thujaplicin,
vitamin, and Na2SeO3 were removed by dialysis
for overnight. Se@TP nanoparticles were sonicated and then filtered
through 0.2 μm pore size. The concentration of SeNPs and TP
was measured by ICP-AES. The morphology and elemental composition
of Se@TP nanoparticles were characterized by transmission electron
microscopy (TEM, H-7650) and EDX (EX-250 system, Horiba). Malvern
Zetasizer software was used to monitor the zeta potential and size
distribution of Se@TP.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
