Binding, Internalization, and Antigen Presentation of Vaccine-Loaded Nanoengineered Capsules in Blood

Nanoengineered microcapsules (shown in green) can be used to encapsulate vaccine antigens conferring protection of the cargo until the capsules are taken up by specialized antigen presenting cells in human blood such as dendritic cells (cell membrane in red, nucleus in blue). This technique offers potential applications for in vivo vaccine delivery.
