Flower-shaped inorganic nanocrystalshave been used for applications in catalysis and ytical science, but so far there have been no reports of ‘nanoflowers’ made of organic components. Here, we report a method for creating hybrid organic–inorganic nanoflowers using copper (II ) ions as the inorganic component and various proteins as the organic com-ponent. The protein molecules form complexes with the copper ions, and these complexes become nucleation sites for primary crystals of copper phosphate. Interaction between the protein and copper ions then leads to the growth of micrometre-sized particles that have nanoscale features and that are shaped like flower petals. When an enzyme is used as the protein com-ponent of the hybrid nanoflower, it exhibits enhanced enzy-matic activity and stability compared with the free enzyme. This is attributed to the high surface area and confinement of the enzymes in the nanoflowers.
