Outline of Final Research Achievements

We synthesized tubular micromotors with a hollow cylindrical structure composed of synthetic polymers and proteins. They are capable of self-propulsion by ejecting oxygen bubbles in an aqueous hydrogen peroxide solution. The inner and outer surfaces of the tube can be freely functionalized post-synthesis. Microtubes coated on their outer surface with fetuin protein successfully captured influenza virus-mimicking nanoparticles. Additionally, the swimming speed of tubes with catalase immobilized on the inner surface could be regulated by visible light irradiation.
