Developing Hwanglyeonhaedok-tang-mediated biosynthesized gold nanoparticles and investigating their immune-enhancing properties in macrophages and splenocytes.

E) PSN1:4:4, ( F) PSN1:8:8. The direction of the arrows represents the position of the hydrogen bond between PTS and EE-PVA. We also investigated the hydro-binding of PTS and nanocarriers using 1H-NMR spectra (Figure 4B–F). We observed several characteristic protons in the PTS 1H-NMR spectra, such as aromatic protons in the regions of δ6.3–7.5 ppm, methyl protons at δ3.8, and hydroxyl protons at δ9.6 (Figure 4B). In addition, Figure 4 shows that the integrated intensity at δ9.6 ppm of PTS was observed in PSN with excipient ratios of 1:2:2 (Figure 4D) and 1:4:4 (Figure 4E); however, ...
