Sphere we go: Unilamellar liposomes containing porphyrin photocatalysts are used to generate novel spherical platinum nanocages. The porous hollow nanospheres are formed by many small joined dendritic platinum nanosheets grown within the confines of the liposomal bilayer. They have 2‐nm thick shells and can have outer diameters up to 200 nm, (see TEM image) making them suitable for catalytic and other applications.
