Bacterial Chemotaxis Reproduced by a Self-Propelled Particle

Key Points

• The aim is to replicate the bacterial chemotaxis behavior of E. coli using a self-propelled particle model.
• Conducted experiments with small self-propelled particles mimicking bacteria
• Developed a simple random walk model for numerical calculations
• Compared results from experiments with findings from numerical simulations
• Experimental behavior of particles aligned well with predicted patterns from the random walk model
• Successful demonstration of how self-propelled particles can mimic chemotactic movement
