The Freigeist group at TU Dresden, led by chemist Dr. Juliane Simmchen, has studied an impressive behavior of synthetic microswimmers: as soon as the photocatalytic particles leave an illuminated zone, they flip independently and swim back into the light. This promising observation and its analysis was recently published in the scientific journal Soft Matter as an “Emerging Investigator” article.
