Abstract: “Living cells in our body present striking complex structures and functions. Inspired by this, biomimetic design approaches for protein microspheres are discussed. The protein microspheres are synthesized using an ultrasonic method. Size control and surface morphology modification is achieved by modulating experimental parameters. The concentration of protein changes the size of microspheres. Different internal oil phase defines the morphology of surface. Nanoparticles are embedded inside and outside of the microspheres, yielding nano-functionalization. Self-assembly for complex structures is also introduced using microspheres as build blocks. The designed microspheres and assembled structures are envisioned to have applications in biomedical, catalyst, and materials sciences.”
