Fig. 2. Characteristics of BNNT/β-glucan complexes and their interactions with IgG. (a) TEM image of BNNT/β-glucan. Scale bar = 1 μm. (b) Complexation between BNNT/β-glucan-PAM and IgG, which was estimated by the upregulation of rhodamine B-labeled BNNT/β-glucan-PAM fluorescence in the presence of FITC-labeled IgG. The molar ratios of BNNT/β-glucan-PAM to IgG were 1 : 0, 1 : 2, 1 : 3, 1 : 4, and 1 : 5. The excitation and emission wavelengths were λem = 495 nm and λem = 540–640 nm, respectively. (c) Cell viability of normal cells (L929) treated with the BNNT/β-glucan complex.
