제목 Dual-Color Emissive Upconversion Nanocapsules for Differential Cancer Bioimaging In Vivo
초록 Early diagnosis of tumor malignancy is crucial for timely cancer treatment aimed at imparting  desired clinical outcomes. The traditional fluorescencebased imaging is unfortunately faced with challenges such as low tissue penetration and background autofluorescence. Upconversion (UC)-based bioimaging can overcome these
limitations as their excitation occurs at lower frequencies and the emission at higher frequencies. In this study, multifunctional silica-based nanocapsules were synthesized to
encapsulate two distinct triplet−triplet annihilation UC chromophore pairs. Each nanocapsule emits different colors, blue or green, following a red light excitation. These nanocapsules were further conjugated with either antibodies or peptides to selectively target breast or colon cancer cells, respectively.
