26. A method of constructing a dendritic cell node comprising:
-
a) depositing, onto a substrate, a layer for attracting monocytes into the dendritic cell node;
b) depositing, onto layer (a), a layer for inducing differentiation of the monocytes into immature dendritic cells;
c) depositing, onto layer (b), a layer for presenting a chosen antigen to immature dendritic cells;
d) depositing, onto layer (c), a layer for attracting dendritic cells and inducing maturation of dendritic cells, thereby constructing a dendritic cell node.
