Experimental Study Simulating Dynamical Features of Escape Panic Using Pt Catalytic Particles

Abstract

We have investigated a steering method to maintain the orientation of active matter that moves by spontaneously breaking the symmetry in a homogenous field. When PVA gel particles loaded with Pt are introduced in a hydrogen peroxide solution, they moves in different directions. In the presence of a concentration gradient of Ag⁺, they exhibit a positive chemotaxis, whereas in the presence of a concentration gradient of Pb²⁺, they exhibit a negative chemotaxis. We utilize this chemotactic motion for safe, feasible and reproducible methods to simulate the dynamical features of escape panic.
