The attraction of the cylindrical hollow (tubular) structure is to provide different functions to the inner pore space, tube wall, and outer surface, independently. We have synthesized protein nanotubes by a unique alternate layer-by-layer assembly technique in a porous polycarbonate membrane. Hepatitis B virus, influenza virus, E. coli, and doxorubicin-loaded liposomes are efficiently incorporated into the inner space of the tube. Placing the enzyme in the innermost layer causes the hydrolysis reaction of the substrate and ring-opening polymerization of the lactone. In addition to proteins and water-soluble polymers, DNA and gold nanoparticles (AnNP) can be used as constituents of the tube wall.
