Abstract
A method for encapsulating a biomacromolecule in a pore-containing polymer comprising the steps of providing an encapsulating solution containing the biomacromolecule and the pore-containing polymer; contacting the biomacromolecule with the pore-containing polymer for a time sufficient for the biomacromolecule to enter the pores of the pore-containing polymer; and rearranging the polymer such that the surface pores of the polymer are closed thus encapsulating the biomacromolecule in the pore-containing polymer.
