A visible fluorescent nanovaccine based on functional genipin crosslinked ovalbumin protein nanoparticles

Schematic illustration of the formulation of fluorescent CS-OVA-NPs and the immune response in vivo. The functional OVA nanovaccine can carry abundant antigens by self-crosslinking of antigens and exert accurate delivery with self-fluorescence. Moreover, the nanoparticles can strengthen cross-presentation in a targeted and sustained release manner to activate antigen-specific T-cells.207
