Abstract:
In this research seminar, I will present my work on active particles and micro/nanorobots conducted
during my PhD and postdoc. The discussion will center on our investigation of active particles, which
display complex self-organization due to their mutual interactions. These particles hold potential for
applications in innovative active materials and specialized fields such as drug delivery,
environmental remediation, and photochromism display. Our research has successfully replicated
biomimetic collective dynamics of active particles, revealing unique functionalities that can be
employed for various purposes. A key part of the seminar will delve into the design of
micro/nanorobots, and the distinct controlling systems utilized to manipulate their motion. By taking
advantage of the properties of materials in constructing these robots, we have developed control
mechanisms based on light, thermal, and magnetic fields for wireless manipulation and motion
programming. Throughout the seminar, I will share examples of active particle fabrication,
micro/nanorobot design, and diverse applications. Our work contributes to the advancement of
biomimetic active systems and opens avenues for future developments in micro/nanorobots and their
applications. By understanding the underlying principles of these systems and the materials used, we
can harness their unique properties and functionalities for practical applications. Ultimately, our
research seeks to bridge the gap between natural and artificial worlds, fostering innovative solutions
for pressing challenges in fields such as medicine and environmental conservation. This research
seminar will demonstrate the potential of active particles and micro/nanorobots in addressing critical
issues, emphasizing the importance of interdisciplinary research in enhancing the capabilities of these
systems.
