UV visible spectral analysis of BNC and various controls within the 400 to 800 nm visible spectral region. (a) PDD ZnPcS₄ 340 nm 125 µm in PBS, whereas final conjugate ZnPcS₄ final concentration remained at 125 µm, (b) final conjugate 520 nm 0.95 × 10¹⁵ AuNP particles/mL (2.99-fold fall), (c) AuNP-S-PEG5000-NH₂ 520 nm 2.85 × 10¹⁵ particles/mL, and (d) PDT ZnPcS₄ 634 and 674 nm 125 µm in PBS, whereas final conjugate is 35 µM ZnPcS₄ concentration (3.54-fold fall).
