Ayusman Sen

About

Ayusman Sen is a pioneering figure in the field of active matter and catalytic nanomotors, whose work bridges chemistry, materials science, and micro-robotics. His research focuses on designing self-propelling micro- and nanoscale systems that harvest chemical energy from their environment to generate motion. Sen’s major contributions include the development of catalytic motors that convert chemical reactions into directed movement, with applications in nanoscale assembly, cargo transport, and biomimetic collective behavior. His highly cited work, “Catalytic Motors—Quo Vadimus?” (86 citations), provides a comprehensive overview of the field’s challenges and future directions. Sen has also advanced the design of titania-based micro/nanomotors (37 citations), demonstrating how these systems can exhibit collective, swarm-like behavior. Notably, his recent work on enzyme-powered pumps (2023) introduces a biocompatible, substrate-specific approach to generating fluid flow, enabling the propulsion of particles and macroscale sheets—a breakthrough for medical and environmental applications. With over 150 publications and numerous awards, Sen’s research continues to inspire new generations of scientists exploring the frontiers of active matter and micro-robotics.
