Autonomous Plasmon-Enhanced Photocatalytic Microrobots Powered by Lorentz Force
The PLOBOT project focused on developing light-driven plasmonic microrobots for precise motion control and enhanced photocatalysis. These microrobots integrate plasmonic and catalytic nanostructures, allowing for autonomous movement and efficient reaction kinetics under light illumination. The project introduced light-induced bipolar electrochemistry as a novel fabrication method, enabling precise material structuring at the nanoscale. This research contributes to sustainable nanotechnology, environmental remediation, and microfluidic catalysis by demonstrating how motion-assisted reactions and plasmonic interactions can improve catalytic efficiency. The findings support the development of programmable microrobots for real-time chemical processes, with applications in water purification, targeted synthesis, and biomedical nanorobotics.

Project objective
The 1966 sci-fi film, Fantastic Voyage, portrayed a scientist who miniaturized a submarine to enter his body to remove a blood clot. It is only recently that scientists have been able to assemble microrobots from scratch to autonomously move and perform complex tasks, such as catching and delivering cargo, and/or performing chemical reactions. The bots use energy from their surroundings or from an external stimulus, and turn it into motion. Light-driven motion in photocatalytic robots is exceptionally appealing as it allows actuation and control by using an external free energy source i.e., sun and enhancement of chemical reactions due to two effects: self-generated micro-mixing effect and constant surface refreshment, giving place to new chemical reactions ‘on-the-fly’. Yet, the reported photocatalytic bots up to date are so slow that their speed can be confused with Brownian motion. This project seeks to combine two approaches for the first time to enhance the efficiency and speed of light-driven bots: Lorentz force as an ultrafast motion mechanism and plasmonic effects for bettering light harvesting. A novel system will be introduced in which the robot’s motion based on the magnetohydrodynamic convection effect is triggered by visible light and can pursue desired reactions (degradation of organic wastes and hydrogen generation). By leveraging the host’s fundamental photophysical approach in nanoplasmonic design and my interdisciplinary angle on microrobots and energy field, the results are expected to bring knowledge gain for the microrobot field, and possibly a long-term impact on Europe’s solar technological innovations. The project‘s training comprises transferrable (leadership and communication) and technical skills development (bridging a knowledge gap in photophysics), to advance my career as a future group leader in Europe with an unorthodox research angle combining photo/electrochemistry and microrobots for alternative energy and environmental solutions.
