Biomaterials can be designed to improve uptake and processing by APCs. A) Pickering emulsions allow for improved deformability, which facilitates uptake of NPs by APCs.

Rigid constructs have prolonged interactions with cells compared to soft constructs. Reproduced with permission.[69] C) Functionalization of polyanhydride NPs with di-mannose via a glycolic acid linker to mimic bacterial surfaces promotes internalization of NPs. Enhanced uptake is observed even with the glycolic acid alone. Copyright 2018, American Chemical Society.
