Design and Numerical Modeling of an On-Board Chemical Release Module for Motion Control of Bacteria-Propelled Swimming Micro-Robots
(2009)Proceedings of the ASME 2008 International Mechanical Engineering Congress and ExpositionOn/off motion control of bacteria-propelled synthetic bodies was previously achieved using a chemical switching technique. A chemical agent (CuSO4) directly binds to the rotor of the flagellar motor inhibiting it. When desired, a second chemical agent (EDTA) is introduced, which binds to the CuSO4 molecules, freeing the motor and allowing the bacteria to resume its motion [1]. To facilitate localized delivery of the control agents and ...Conference Paper -
Towards Hybrid Swimming Microrobots: Bacteria Assisted Propulsion of Polystyrene Beads
(2006)2006 28th Annual International Conference of the IEEE Engineering in Medicine and Biology SocietyCompactness and efficiency of biomotors makes them superior to man-made actuators and a very attractive choice of actuation for micro/nanorobots. However, biomotors are difficult to work with due to complications associated with their isolation and reconstitution. To circumvent this problem, here we use flagellar motors inside the intact cell of S. marcescens bacteria. An array of bacteria is used as propeller for a 10 mum polystyrene ...Conference Paper
