Porogens used to generate pores in the PHEMA-PEGDA include water (W), sucrose solution (S), and benzyl alcohol (BOH).

This table shows the % v/v quantity of components used to create the PHEMA-PEGDA structures. The deionized water content (% v/v) listed shows the total aqueous content of the final pre-polymerized mix of monomers and other agents. As porogen types and volumes were adjusted, the quantities of PHEMA and PEGDA monomers remained constant.
