A “Biomembrane”is a key interface to integrate production and separation of target materials through the creationof “new order”on its surface. A model biomembrane, liposome, can recognize (separate)the (bio)moleculesthrough (i)electrostatic, (ii)hydrophobic interaction, and (iii)stabilization effect of hydrogen bonds in the hydropho-bic lipid environment. A novel biomembrane-based catalysis (LIPOzyme: liposome + enzyme)can be designed anddeveloped by integrating the above recognition sites and a simple catalytic center on the liposome surface. A processdesign utilizing LIPOzyme chemistry and the recognition (bioseparation)functions of model-biomembrane (lipo-some)is the basic strategy to achieve a “Biomembrane Process Chemistry”as an application of “Membranomics”.
