| Outline of Final Research Achievements |
We have synthesized microtube (MT) motors with a cylindrical hollow structure consisting of proteins. The MT with catalase on the inner surface was self-propelled by jetting oxygen bubbles generated by the disproportionation of hydrogen peroxide. The MT with urease interior surface was self-propelled by ejection of the product generated by the decomposition of urea. Furthermore, the MT motors coated with concanavalin A captured Escherichia coli. The MT motors coated with α-glucosidase acted as a self-stirring catalyst. The MT motor coated with fetuin captured efficiently the spike protein of influenza virus. In addition, the self-propelling velocity of MT coated with gold nanoparticles increased by light irradiation.
