The results of the analysis of the mean square displacement and the trajectories of moving polymer particles with a modified surface in a dusty plasma monolayer under the influence of laser radiation are presented. It has been revealed that the dynamics of particle motion in a monolayer consists of three modes: finite motion within confinement, Brownian motion, and combined directional chaotic motion. The results of the analysis of linear displacement along and across the direction of motion of dust particles at various values of the laser radiation power are presented too. It has been shown experimentally that polymer particles with a modified surface are active Brownian particles and their activity grows with increasing laser radiation power.
