Fig. 1. Schematic illustration of the two-step method used to prepare the tumor-selective BNNT/β-glucan complex conjugated to a HER-2-targeting antibody (BNNT/β-glucan-IgG). [1] A boron nitride nanotube and a Protein A mimic bearing β-1,3-glucan (β-glucan-PAM) were complexed via the facile HSVM method. [2] The HER-2-targeting antibody was conjugated to BNNT/β-glucan using the binding ability of the Protein A mimic moiety.
