Abstract

This paper describes a method of producing a rotating flagella array. Flagella of unicellular algae Chlamydomonas were released from the cell body, and selectively fixed on the glass substrate where methacryloyloxyethylphosphorylcholine (MPC)-polymer was patterned in order to prevent non-specific binding. They were then reactivated and rotated like micro motors when ATP was added. Using this experimental set-up, we monitored single flagellum continuously on site and changed its rotating speed by controlling the concentration of Ca2+. We believe that rotating flagella can be utilized as actuators for various microfluidic devices.
